Abstract

We demonstrate programmable all-optical nonlinear functions using a microring resonator integrated with a saturable absorber on a generic InP platform. The device exhibits programmable behavior resembling radial basis, clamped ReLU, sigmoid, and softplus-like functions. Simulations on the MNIST classification using measured responses achieve over 94% accuracy.
