Abstract: A solid state photonics circuit having a liquid crystal (LC) layer for beam steering. The LC layer can provide tuning of an array of waveguides by controlling the application of voltage to the liquid crystal. The application of voltage to the liquid crystal can be controlled to perform beam steering with the light signal based on different tuning in each of the waveguides of the array. The waveguides are disposed in a substrate having an oxide or other insulating layer with an opening. The opening in the oxide layer exposes a portion of a path of the array of waveguides. The waveguides are exposed to the liquid crystal through the oxide opening, which allows the voltage changes to the liquid crystal to tune the optical signals in the waveguides.

Abstract: An optical circuit includes solid state photonics. The optical circuit includes a phased array of solid state waveguides that perform beamsteering on an optical signal. The optical circuit includes a modulator to modulate a bit sequence onto the carrier frequency of the optical signal, and the beamsteered signal includes the modulated bit sequence. The optical circuit includes a photodetector to detect a reflection of the beamsteered optical signal. The optical circuit autocorrelates the reflection signal with the bit sequence to generate a processed signal.
