Abstract:
The manipulation of femtosecond laser light inside transparent media can be directed on varying interaction pathways of microexplosions, photochemistry, and self-focusing filamentation to open new directions for creating dense memory storage, three-dimensional (3D) optical circuits, 3D microfluidic networks and high-speed scribing tracks. The presentation follows these fundamental interactions towards controlling laser processes in transparent glasses, particularly in optical fibers and thin films that enable highly functional and compact devices to form with the benefits of seamless integration with single mode optical fibers or microelectronic chips.  The concept of forming 3D optical circuits within the fiber cladding is presented together with the means for coupling light efficiently with the fiber core waveguide. Chemical etching of laser-generated nanogratings are used to embed microfluidic channels, micro-optical devices and optical resonator components.  The laser writing overall provides a flexible integration of fiber-cladding photonics and microfluidics on which to build 3D opto-fluidic microsystems in our common base of optical networks through to minimally invasive biomedical probes.  The approach promises to reduce fabrication and packaging costs and to enable highly functional all-fiber microsystems for optical communications, fiber lasers, and sensing.  Examples of integrated approaches in lab-in-a-fiber devices, smart medical catheters, and lab-in-film devices are presented.

How to Win Electrons’ Friendship and Make Them Dance for You


In the realm of electrons, in atoms and molecules, things happen fast. According to Bohr’s planetary model for the hydrogen atom, for example, the “sidereal year’’, i.e., the time it takes to the electron to complete the shortest orbit around the nucleus, has the fantastically small duration of 152 attoseconds (as; 1as = 10-18 s).  This estimate remains true even when formulated in the language of quantum mechanics. Such ultrafast motion could not be directly confirmed until, at the turn of this century, groundbreaking advancements in laser technology led to the production of flashes of light with sufficiently short duration (the world record is 67 as) to take clear snapshots of it.

In systems bigger than hydrogen, the same Coulomb force that binds an electron to the nucleus also acts repulsively between electrons. The main effect of such repulsion is to screen the nuclear charge, thus reducing the binding energy of each individual electron. To a first approximation, therefore, in several complex systems, electrons can act as if they were independent. As a result, their motion may appear not much more complicated than the one observed in the hydrogen atom. In fact, most of the experiments carried out so far to follow the electronic movement could set in motion only one electron at a time, thus confirming this picture.

Electrostatic repulsion, however, has also a secondary, subtler effect. In the same way as a bus passenger avoids not only to sit next to the other passengers, if she can, but also to bump into them as she walks down the isle, electrons try to avoid each other as they move across an atom or a molecule: the motion of the electrons is correlated. Keeping each other at arm’s length, electrons minimize their mutual repulsion and, as a consequence, they stabilize the ground state of the atom or molecule to which they belong. Such stabilization influences the energy balance of all natural processes, and is key to our understanding and control of matter, from energy transfer in photosynthetic systems, to the inner workings of futuristic quantum computers.  Correlation alters even more dramatically the dynamics in excited states, where pairs of electrons move in unison. Until recently, such concerted motion eluded direct experimental observation. By combining flashes of extreme ultraviolet and visible laser light with a duration of only a few hundred attoseconds and timed very accurately with respect to each other, however, it was eventually shown that monitoring and controlling this motion is in fact possible.

In this colloquium I will illustrate with examples taken from my research on the helium atom, a prototype of poly-electronic systems, how attosecond spectroscopies have opened the road that leads to the direct observation and control of correlated electronic motion in matter.

Abstract:
Over the last two decades laser additive manufacturing (LAM) technological communities have made considerable efforts, developing scientific and technological elements necessary for rapid and reliable production of near net shape components with desired properties and capabilities and with minimum cost and lead-time possible. LAM technology has opened up alternative possibilities for the manufacture of end-use components as well as the reuse of legacy components.  Metallic components are directly made from CAD dimension by melting metal powders pixel-by-pixel utilizing a laser, maintaining dimensional accuracy and material integrity utilizing a closed-loop feedback control.  Expanding LAM into high-value safety-stringent applications, next-level of complexities and challenges, such as real-time control of LAM to improve dimensional accuracy to minimize post-processing, real-time minimization of residual stress, in-situ monitoring and control of microstructure to obtain desired properties and performance, methodology to derive desired mechanical properties, and real-time quality control through in-situ inspection, need to be facilitated and addressed in terms of scientific know-how and manufacturing efficiency.  This presentation summarizes and discusses LAM advancements throughout two decades of R&D efforts carried out through lab environments and real-world settings, facilitating those complexities.

Abstract: 
Crystallization from glass can be a powerful process to elaborate innovating transparent materials for optical and photonic applications if nucleation and crystal growth steps can be precisely controlled. This talk will focus on two main applications: transparent polycrystalline ceramics elaborated by full and congruent crystallization from glass and nanostructured glass-ceramics designed from nanoscale phase separated glasses.
Transparent polycrystalline ceramics elaborated by full crystallization from glass
Transparent polycrystalline ceramics are an emerging class of photonic quality materials competing with single crystal technology for a diverse range of applications including high-energy lasers, scintillating devices, optical lenses, and transparent armor. Polycrystalline ceramics offer several advantages, particularly in the fabrication of complex shapes and large-scale industrial production, and enable greater and more homogenous doping of optically active ions than is possible in single crystals. However, up to date, only a limited number of such materials has been reported. These are either cubic or nanocrystalline transparent polycrystalline ceramics which require complex, time-consuming and so expensive synthetic approaches.
Our recent work shows the possibility to obtain transparent polycrystalline ceramics by full and congruent crystallization from glass. Transparency is observed despite micrometer scale crystals and a non cubic symmetry (no structural isotropy) of the crystalline phase. Interestingly, crystallization from glass can give access to new crystalline phases given the relatively low crystallization temperature compared to classic solid state elaboration temperature. This is demonstrated in the case of a new composition, BaAl4O7, showing the existence of two orthorhombic polymorphs both showing high transparency in the visible and infra-red ranges [1,2]. The crystallographic structures of these polymorphs have been determined ab initio from powder diffraction data. From these structural models, the optical birefringence has been obtained by DFT calculations of the dielectric function. These results enable to discuss the transparency property of these materials as a function of the determined crystalline structures and the observed microstructures. Remarkably, these materials show promising scintillation properties when doped by europium [3]. The same elaboration process has been applied to cubic compositions, Sr3Al2O6 and Sr3Ga2O6, allowing very high transparencies to be attained [4]. Lastly, we have focused our work on strontium aluminosilicate compositions, the addition of silica enabling large scale glass samples to be obtained. The full and congruent crystallization of Sr1+x/2Al2+xSi2-xO8 compositions leads to new transparent polycrystalline ceramics forming a crystalline solid solution exhibiting hexagonal symmetry. These materials show an impressive transmittance higher than 90%, which sets a transparency record for oxide ceramics. A crystallographic study coupled to NMR experiments and DFT calculations of the birefringence allowed us to evidence the role of structural disorder (Al/Si substitution and presence of vacancies on strontium sites) in the origin of the optical isotropy observed in these structurally anisotropic materials. These results propose an innovative concept, the addition of a controlled structural disorder within crystalline structures, in order to lower the birefringence and to elaborate new transparent ceramics [5].

New nanostructured gallogermanate- and gallosilicate-based glass materials exhibiting high transparency in the visible range have been fabricated by conventional melt-quenching. These materials can accommodate wide oxide compositions and present nanoscale phase separation. The size of the nanostructuring can be tailored depending on the nominal composition. A single heat treatment then allows selective crystallization of the phase separated glass, resulting in glass-ceramic materials exhibiting nanostructures and transparency similar to the parent glass.[6,7]
The wide possibilities of designing new nanostructured glass-ceramics with tunable optical properties will be illustrated in the case of a highly transparent ZnGa2O4 glass-ceramic exhibiting 50 wt% of nanocrystals with homogeneous and tunable sizes. High resolution scanning transmission electron microscopy analysis coupled with in situ high temperature X-ray diffraction and optical measurements led to a detailed description of the crystallization process. Remarkably, red long-lasting luminescence arising from the entire sample volume is observed in this Cr3+ doped material, opening the route to a wider range of performing applications for this famous zinc gallate persistent phosphor.[8,9]

Abstract
Progress of the current hybridized photon-electron communication technology has been slowed down by the limited efficiency of electrical interconnects. While optical interconnects is a viable solution, it falls short to offer an efficient long term solution, since logic operations will be performed using electrons. Optical interconnects in conjunction with excitonic circuits offer a plausible solution since it not only overcomes the losses and delays experienced by electrons but also benefits from seamless transformation between an exciton and a photon.
In my talk, I will discuss the importance of reconfigurable optical nanocavities for on-chip optical interconnects. In particular, I will talk on photonic crystal nanobeam cavities and discuss an all-optical reconfiguration technique based on optical gradient force. I will introduce the benefits of excitonic circuits and discuss a technique to visualize exciton diffusion, an important parameter for designing excitonic devices. I will also discuss an excitonic modulator based on charged excitons (trions) in tungsten diselenide (WSe2) monolayer. Such opto-excitonic circuits open a new way to process information reaping the benefits of unprecedented energy efficiency offered by a photon as an information carrier.

Abstract: 
The search for producible materials with simultaneous occurrence of superior thermo-mechanical properties and long-wave infrared (LWIR) transmission has been a longstanding problem in infrared ceramics engineering.  Recent research has suggested the possibility of using chalcogenide glass processing as a means to achieve breakthroughs in this area.  This talk will focus on three aspects of this problem.  1) vision and scoping experiments for fully ceramized LWIR glass ceramics based on sulfide glasses; 2) prediction methods of optical properties of multicomponent IR glasses; and 3) comparative topological effects on structural and optical properties of ternary Ge-based chalcogenide glasses. 

Long-wave Infrared Transmitting Glass-Ceramics
Three sulfide systems were explored including two with La2S3 in hopes of imparting strong bonds from this refractory sulfide, and two containing GeS2 in hopes of widening the glass-forming region. Attempts were made to produce glasses in the Ga2S3-La2S3-(ZnS,CaS) system, the GeS2-La2S3 system, and the GeS2-Ga2S3-CdS system. Microstructural and thermal analyses were used to explore nucleation and growth in these systems and infrared transmission and mechanical hardness showed potential for LWIR window use. The GeS2-Ga2S3-CdS system showed good LWIR transmission and pre-crystallized hardness superior to chemical vapor deposited ZnS. The Ga2S3-La2S3 glasses did not appear to be viable candidates at this time due to strong tendency for phase separation, a small temperature window between crystallization and glass transition temperatures, and problems with oxygen contamination in the La2S3 source. Glass formation in these materials is shown to be a strong function of quenching method and raw materials.  Suggestions are made for alternative methods for producing fully ceramized LWIR-transmitting glass ceramics. 

Optical Property Prediction in Infrared Glasses
It is often useful to obtain custom glasses that meet particular requirements of refractive index and dispersion for high-end optical design and applications.  In the case of infrared glasses, limited experimental data are available due to difficulties in processing of these glasses and also measuring refractive indices accurately.  Methods for estimating refractive index and dispersion as a function of composition for selected infrared-transmitting glasses are reviewed and evaluated, including Gladstone-Dale, Wemple-DiDomenico single oscillator, Optical basicity, and Lorentz-Lorenz total polarizability.  Various estimates for a set of PbO-Bi2O3-Ga2O3 (heavy metal oxide) and As-S (chalcogenide) glasses are compared with measured values of index and dispersion.  Problems associated with known glass topology changes and index prediction are discussed.      

Topological Effects on Properties of Ge-based Ternary Chalcogenide Glasses
Germanium based ternary chalcogenide glasses have been explored for over 50 years.  However, glass scientists are still discovering the complexities of these systems, particularly in relation to the continuum between random covalent network (RCN) and chemical ordered covalent network (COCN) structures. Recent understanding of crystal precipitation in these glass systems has aided in understanding of the medium range ordering.  In this final part of the talk, a comparison is made between the behavior of glass transition versus average coordination number for known compositions in Ge-Ga-Se, Ge-Ga-S, Ge-Sb-Se, and Ge-As-Se systems.
