摘要： One example includes an optical device system. The system includes a waveguide that includes a fixed waveguide portion to propagate an optical signal, a semiconductor membrane layer, and a tunable air gap that separates the fixed waveguide portion and the semiconductor membrane layer. The system also includes an optical tuning system to move the semiconductor membrane layer with respect to the fixed waveguide portion in response to a control signal to control a separation distance of the tunable air gap to tune a characteristic of the optical signal.

摘要： 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.
