Abstract:
Like a tuning fork for light, optical resonators have a characteristic set of frequencies at which it is possible to confine light waves. At these frequencies, optical energy can be efficiently stored for lengths of time characterized by the resonator Q factor, roughly the storage time in cycles of oscillation. In the last ten years there has been remarkable progress in boosting this storage time in micro and millimeter-scale optical resonators. Chip-based devices have attained Q factors of nearly 1 billion and micro-machined crystalline devices have provided Qs exceeding 100 billion. The resulting long, energy-storage times combined with small form factors have made it possible to access a wide range of nonlinear phenomena and to create laser devices that operate with remarkably low turn-on powers. Also, new science has resulted from radiation-pressure coupling of optical and mechanical degrees-of-freedom in the resonators themselves. I will review some of these results including parametric oscillators, optical frequency microcombs and microwave generation. The adaptation of resonator fabrication methods to optical delay lines as long as 27 meters on a silicon wafer will also be discussed.

Biography:
Professor Vahala received his BS, MS and Ph.D. degrees at Caltech. His research group has pioneered a class of optical resonators that hold the record for highest optical Q on a semiconductor chip.  They have applied these devices to study a wide range of nonlinear phenomena including the first demonstration of parametric oscillation in a micro cavity, now the basis for frequency micro combs. His research in this subject also led to the demonstration of dynamic backaction, a long-anticipated interaction of mechanics and optics mediated by radiation pressure that is responsible for opto-mechanical cooling and recent realizations of mechanical amplification by stimulated phonon emission.  Professor Vahala was involved in the early effort to develop quantum-well lasers for optical communications and received the IEEE Sarnoff Award for his research on quantum-well laser dynamics. He has also received an Alexander von Humboldt Award for his work on ultra-high-Q optical microcavities and is a fellow of the IEEE and the Optical Society of America.

Abstract:
A fluorochlorozirconate (FCZ) glass-ceramic containing orthorhombic barium chloride crystals doped with divalent europium was evaluated for use as a storage phosphor in gamma-ray imaging. X-ray diffraction and phosphorimetry of the glass-ceramic sample showed the presence of a significant amount of orthorhombic barium chloride crystals in the glass matrix. Transmission electron microscopy and scanning electron microscopy were used to identify crystal size, structure, and morphology.  The size of the orthorhombic barium chloride crystals in the FCZ glass matrix was very large, ~0.5-0.7 μm, which can limit image resolution. The FCZ glass-ceramic sample was exposed to 1 MeV gamma rays to determine its photostimulated emission characteristics at high energies, which were found to be suitable for imaging applications.  Test images were made at 2 MeV energies using gap and step wedge phantoms. Gaps as small as 101.6 µm in a 440 stainless steel phantom were imaged using the sample imaging plate. Analysis of an image created using a depleted uranium step wedge phantom showed that emission is proportional to incident energy at the sample. The results showed that the sample imaging plate has potential for gamma-ray computed radiography and dosimetry applications.
Keywords: functional composites; glasses; ceramics; non-destructive testing.

Biography:
Dr. Johnson completed her doctorate in solid state physicsin the research area of magnetic phase transitions at the University of Liverpool in 1985. She transitioned to working on glass materials after being approached by Pilkington Glass to solve technical problems. She was a Professor in Liverpool until 1995 when she joined Argonne National Laboratory in the United States, where she was introduced to solving the structure of amorphous materials using neutron scattering. After a 2-year period in administration she returned to research to develop a new mammography system using a glass-ceramic plate. In 2007, Dr. Johnson returned to academia at the University of Tennessee Space Institute and continues to synthesize and characterize glasses, glass ceramics and nanomaterials pertaining to medical devices, non-destructive evaluation and image enhancement.

TOMORROW! NSTC/CREOL Distinguished Seminar Series: “Soft Optoelectronics: From Brain Interfaces to Fly’s Eye Cameras”- John Rogers 1.22.15/10:30-11:30am/ CREOL RM 102/103

NSTC/CREOL Distinguished Seminar Series: “Soft Optoelectronics: From Brain Interfaces to Fly’s Eye Cameras”- John Rogers
Thursday, January 22, 2015 10:30 AM to 11:30 AM
CREOL 102/103

Celebrating the International Year of Light 2015

Abstract:
Recent advances in materials science and mechanical engineering enable construction of high performance optical, electronic and mechanical microsystems that can flex, bend, fold and stretch, with ability to accommodate large (>>1%) strain deformation with a purely elastic mechanical response.  Such technologies open up new engineering opportunities in bio-inspired device design and in intimate, multifunctional interfaces to the human body. This talk summarizes fundamental and applied aspects of two recent examples: (1) hemispherical digital imagers that incorporate essential design features found in the arthropod eye and (2) injectable, cellular-scale light emitting diodes for wireless control of complex behaviors in animal models, via the techniques of optogenetics.

Biography:
 Professor John A. Rogers obtained BA and BS degrees in chemistry and in physics from the University of Texas, Austin, in 1989.  From MIT, he received SM degrees in physics and in chemistry in 1992 and the PhD degree in physical chemistry in 1995.  From 1995 to 1997, Rogers was a Junior Fellow in the Harvard University Society of Fellows.  He joined Bell Laboratories as a Member of Technical Staff in the Condensed Matter Physics Research Department in 1997, and served as Director of this department from the end of 2000 to 2002.  He is currently Swanlund Chair Professor at University of Illinois at Urbana/Champaign, with a primary appointment in the Department of Materials Science and Engineering.  He is also Director of the Seitz Materials Research Laboratory. Rogers’ research includes fundamental and applied aspects of materials and patterning techniques for unusual electronic and photonic devices, with an emphasis on bio-integrated and bio-inspired systems.  He has published more than 450 papers and is inventor on over 80 patents, more than 50 of which are licensed or in active use.  Rogers is a Fellow of the IEEE, APS, MRS and AAAS, and he is a member of the National Academy of Engineering and the American Academy of Arts and Sciences.  His research has been recognized with many awards, including a MacArthur Fellowship in 2009, the Lemelson-MIT Prize in 2011 and, in 2013, the MRS Mid-Career Researcher Award, the ASME Robert Henry Thurston Award and the Smithsonian Award for American Ingenuity in the Physical Sciences.  In 2013 he also received an Honoris Causa Doctorate from the École Polytechnique Fédérale de Lausanne.
