Abstract: Systems, devices, and methods are provided for built-in redundancy in optical devices that output an optical signal, for example, to photonic integrated circuits. The device and systems disclosed herein include a plurality of optical sources coupled to a plurality of waveguides. Each adjacent pair of the plurality of waveguides are coupled to an optical switching devices that comprises an interferometer having a first branch comprising a phase-shift mechanism coupled to one waveguide of the pair of waveguides. A voltage bias can be applied to the phase-shift mechanisms to tune a respective phase difference and direct an optical signal from any of the plurality of optical sources to the output end of the optical device. According to various examples disclosed herein, the phase-shift mechanisms comprises metal oxide semiconductor (MOS) capacitors.

Abstract: Systems and methods are provided for performing element-wise multi-vector multiplication. An example includes a waveguide to receive an input optical signal encoded with a first vector and output an output optical signal. One or more optical-to-electrical (O/E) converters are provided to receive one or more optical signals encoded with one or more vectors and generate one or more electrical signals based on the received one or more optical signals. One or more optical modulators are optically coupled to the waveguide and electrically coupled to the one or more O/E converters, the one or more optical modulators modulate an intensity of the input optical signal on the waveguide based on the one or more electrical signals. The output optical signal is encoded with a product of the first vector and the one or more vectors.
