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.
