Chip-Based Stimulated Brillouin Scattering for Low-Power Microwave Photonic Signal Processing Applications

Talk Title: Chip-Based Stimulated Brillouin Scattering for Low-Power Microwave Photonic Signal Processing Applications

Abstract: The last few years have seen major progress in harnessing on-chip photon-phonon interactions, leading to a wide range of demonstrations of new functionalities. Utilizing not only the optical response of a nonlinear waveguide - but also hypersound acoustic resonances - enables the realization of microwave devices with unprecedented performance. Here we overview on-chip Stimulated Brillouin scattering (SBS) with special emphasis on reconfigurable and broadband microwave signal processing schemes. We review the different material platforms and structures for on-chip SBS, ranging from chalcogenide rib waveguides to CMOS compatible hybrid silicon/silicon-nitride structures and silicon nanowires. We show that the paradigm shift in SBS research - from long length of fibers to chip scale devices - is now moving towards fully integrated photonic-phononic CMOS chips.

Biography: Professor Benjamin Eggleton is an ARC Laureate Fellow and Professor of Physics at the University of Sydney and Director of the ARC Centre for Ultrahigh bandwidth Devices for Optical Systems (CUDOS). He obtained his PhD degree in Physics from the University of Sydney, in 1996 and then joined Bell Laboratories, Lucent Technologies as a Postdoctoral Member of Staff. In 2000, he was promoted to Director within the Specialty Photonics Division of Bell Laboratories, where he was engaged in forward-looking research supporting Lucent Technologies business in optical fiber devices. He returned to the University of Sydney in 2003 as the founding Director of CUDOS and Professor in the School of Physics.
