Realization of All-Optical Nonlinear Activation Function in Photonic Nano-Beam Resonators for Application in Optical Neural Networks
This study presents the development of a novel nonlinear activation function (NLAF) for integrated optical neural networks (ONNs), leveraging a thermally actuated photonic crystal (PC) nanobeam resonator (PCNBR) integrated with a phase-change material (GST). For the first time, t…
