Abstract: Implementations disclosed herein provide for devices and methods for obtaining parity time (PT) symmetric directional couplers through improved phase tuning, along with separate optical gain and optical loss tuning. The present disclosure integrates phase tuning and optical gain/loss tuning structures into waveguides of directional couplers disclosed herein. In some examples, directional couplers disclosed herein integrate one or more hybrid metal-oxide-semiconductor capacitors (MOSCAPs) formed by a dielectric layer between two semiconductor layers that provide for phase tuning via plasma dispersion and/or carrier accumulation depending on voltage bias polarity, and one or more optically active medium that provide for optical gain or loss tuning depending on voltage bias polarity.

Abstract: Systems and methods are provided for devices and methods for implementing an optical neural network (ONN) by leveraging resonator structures, such on micro-ring resonators (MRRs). Examples include unit cells configured to perform a linear transformation on optical signals. Each unit cell comprises a plurality of signal mixing components optically coupled to between adjacent waveguides, where each signal mixing component corresponds to a distinct wavelength and is configured to mix optical signals on the adjacent waveguides at the distinct wavelength. Each unit cell also includes a plurality of phase tuning components each corresponding to a distinct wavelength and configured to adjust a phase of a mixed optical signal at the distinct wavelength.
