Abstract
An apparatus and methods are provided for an optical neural network architecture that utilizes parity-time (PT) symmetric couplers. The example PT symmetric optical neural network is based on layers using the PT symmetric couplers that each have two parallel waveguides. One waveguide applies gain while the other waveguide applies an equal loss to signals.
