Abstract:

Liquid crystal mixtures with very high birefringence were designed for microwave applications. They show high tuning ranges, very low dielectric losses and high reliability against heat stress. Using those mixtures, LC-based microwave components and devices, such as phase shifter, tunable filter, and phased array antennas can be realized.

Abstract:

In recent years, High-order Harmonic Spectroscopy (HHS) has proven to be a powerful means to investigate ultrafast dynamics in small molecules. However discrepancies between experimental results and theoretical predictions motivate the development of ever more precise experimental setups, in particular to measure the phase of the attosecond emission. In this talk I will present two multi-dimensional HHS experiments based on the use of a very stable two-source interferometer.

SWIFTS: a groundbreaking integrated principle for high-performance spectroscopy and optical sensors

Christophe BONNEVILLE, PhD

Abstract

SWIFTS, or Stationary-Wave Integrated Fourier Transform Spectrometer, is a new, highly integrated high-resolution spectroscopy technology that represents a major advance in the field. It is based on a new way of probing an optical standing wave formed by the light to be analyzed without scanning or moving parts. SWIFTS combines groundbreaking nanotechnology research, integrated optics, microelectronics and embedded software, resulting in high-resolution spectrometer technology bundled into a single robust device measuring a few mm². The story of the commercialization of this technology will be part of the presentation. The technology has been implemented into first products providing a high-resolution high-rate solution for the characterization of lasers. It allows for the first time a dynamic view of their behavior. SWIFTS is also the starting point for breakthrough solutions to address Bragg sensing, high-depth Optical Coherent Tomography and Raman Spectroscopy.

Abstract:

For the last 25 years, Microwave Photonics (MWP) systems and links have relied almost exclusively on discrete optoelectronic devices and standard optical fibers and fiber-based components which have been employed to support several functionalities like RF signal generation, distribution, processing and analysis. These configurations are bulky, expensive and power-consuming while lacking in flexibility. A second generation, termed as Integrated Micro-wave Photonics (IMWP) which aims at the incorporation of MWP components/ subsystems in photonic circuits, is crucial for the implementation of both low-cost and advanced analog optical front-ends and, thus, instrumental to achieve these targets. After reviewing the basic principles of microwave photonics (MWP) for the non-specialized technical audience, this lecture states the case for the integrated approach towards MWP and overviews the available technology platforms (InP, silicon, silica, silicon nitride, chalcogenides etc..) for the implementation of MWP photonic integrated circuits(PICs), outlining the main features advantages and limitations for each one.

The lecture then reviews the salient research results reported during the last years in several applications and the different platforms (MWP link, signal processing and filtering, signal generation, delay lines, phase-shifters and beam-formers etc..) and finally introduces the concept of the MWP transistor, a multipurpose signal processor architecture which allows for the implrmrntation of all the main basic MWP functionalities. The lecture is concluded with a summary and considerations on the future directions of this field.
