Programmable, high-speed all-optical nonlinear activation functions for neuromorphic photonics
Aashu Jha, Chaoran Huang, Paul R. Prucnal · 2021
We experimentally demonstrate programmable, all-optical nonlinear activation functions, including: rectified linear unit (ReLU), inverse-ReLU and quadratic functions, on a silicon-nitride platform at a remarkable speed of 10 Gbps, enabling real-time processing on all-purpose photonic hardware.
