Recent progress in chip-based nonlinear optics - 20 September 2013

Professor Benjamin J. Eggleton, Centre for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS), The University of Sydney, Australia

The Zepler Institute hosted a guest lecture from Professor Benjamin J. Eggleton, Professor of Physics, ARC Laureate Fellow, Director of CUDOS – ARC Centre of Excellence for Ultrahigh-bandwidth Devices for Optical Systems and Director of the Institute of Photonics and Optical Science (IPOS) on Friday 20 September 2013. The lecture entitled 'Recent progress in chip-based nonlinear optics' was followed by a questions and answer session.


We review recent progress in inducing and harnessing Stimulated Brillouin Scattering (SBS) in integrated photonic circuits. Exciting SBS in a chip-scale device is challenging due to the stringent requirements on materials and device geometry. The dependence of SBS on critical material parameters, such as optical refractive index and acoustic velocity, as well as device properties such as acousto-optic confinement, is discussed. Recent work on SBS in nanophotonic waveguides is presented, with special attention paid to photonic integration of applications such as slow- and fast-light, microwave signal processing, Brillouin dynamic gratings and non-reciprocal devices.
