PORT: Piezoelectric Optical Resonant Transducer
Presenter: sunil bhave
, Purdue University
Microwave frequency stress-optic modulation up to 9 GHz of silicon nitride microring is achieved by exciting bulk acoustic waves piezoelectrically. The acoustic waves are confined tightly in the oxide cladding which enhances the acoustic energy density, modulation efficiency, and opens up opportunities for PORT in chip-scale frequency combs, LIDAR and microwave-to-optical conversion.Authors: sunil bhave, Purdue University

Neuromorphic Silicon Photonics and Applications
Presenter: Paul Prucnal
, Princeton University
The growth of AI computing has been closely correlated with hardware innovations. After GPUs were first used in machine learning in 2009, the computational and data requirements for new AI algorithms have been doubling every 4 months. Realizing the potential environmental and energy impact of this rampant growth, the industry accelerated the call for more efficient algorithms and hardware alike. This has motivated the creation of the field of neuromorphic photonics. Here, we would like to focus on specific advantages of photonic implementation of neural networks, e.g. well known high bandwidth and parallelism. One very promising advantage, often overlooked, is latency. Neuromorphic photonics can take a trained low-speed neural network and offer a very low and deterministic processing latency, on the order of nanoseconds, when implemented in hardware. A low latency processor is crucial in applications such as high-speed feedback control and real-time RF processing.Authors: Paul Prucnal, Princeton University / Thomas Ferreira de Lima, Princeton University / Bhavin Shastri, Queen's University
