Abstract
A device system for constituting a 3D image sensor based on optical phased array is provided. The device system includes an optical modulator that is integrated on the same photonic integrated circuit (PIC) chip as a laser diode array with different output wavelengths and a multiplexer for transmitting an optical wave having a wavelength selected from the laser diode array to an optical waveguide and modulates the optical wave into a specific optical signal, an optical phased array that radiates the optical signal received via an optical switch to the free space using a tunable transmit and receive (TRx) antenna array, and a photodetector that converts an Rx optical signal received by a Tx optical signal transmitted via the optical phased array into an electrical signal.
