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.

Abstract: Examples herein relate to single-etch layer grating couplers. In particular, implementations herein relate to single-etch layer grating couplers comprising a planar waveguide wherein a first grating section and a second grating section are etched into. The first grating section is configured to scatter light at a given wavelength at a first angle relative to vertical and the second grating section is configured to scatter light at the given wavelength at a second angle relative to vertical. The stagger-tuning of the first grating section and the second grating section results in the light at the given wavelength being scattered at a desired angle the same or near an angle at which an optical fiber is offset from vertical.

Abstract: Systems and methods are provided for general matrix multiplication using wavelength parallel processing of a photonic tensor core. Examples of the systems and methods disclosed herein include encoding a second matrix into a plurality of optical signals based on a plurality of free spectral ranges (FSRs) of an array of resonator structures, the resonator structures having resonances tuned based on a first matrix. The optical signals can be input into input waveguides optically coupled to the array of resonator structures. A third matrix, representative of the first matrix multiplied by the second matrix, can be generated based on optical power output from the array of resonator structures.
