With the increase in demand for bandwidth, the current wireless communication networks are reaching a bottleneck. Microwave photonics combines the advantages of microwave electronics and photonics, enabling larger bandwidths and increased flexibility. However, there are requirements for high-resolution signal processing and high-performance metrics including low noise figure, low insertion loss and high dynamic range that need to be met.
In this talk, I will outline our efforts to solve these problems using the well-known nonlinear optical process based on light-sound interaction, stimulated Brillouin scattering (SBS) in a photonic chip. I will also discuss the potential applications of SBS in optical communication networks, both at the transmitter-end using optical frequency combs and at the receiver-end using low-latency optical circuits.
Amol is a DECRA Fellow at the School of Physics, University of Sydney, where he is developing novel on-chip frequency combs that can be processed using integrated nonlinear optics for telecommunications. He holds a PhD in Optoelectronics from the Optoelectronics Research Centre, University of Southampton. After graduating, he received an EPSRC Doctoral Prize fellowship to work on graphene-based pulsed waveguide lasers. His research areas of interest are integrated optics, microwave photonics, non-linear optics, optical communications, and laser physics. He serves on the Conference Committees of CLEO USA, ACP, LAOP, Photonic-India, SPIE Photonics Europe and SPIE OP18. He is the 2018 recipient of the OSA’s Ivan P. Kaminow Outstanding Early Career Professional Prize.
