Device system for constituting 3D image sensor capable of wireless data transmission and reception based on optical phased array

A device system for constituting a 3D image sensor capable of performing wireless data transmission and reception of a modulated optical signal based on optical phased array, the device system comprising:

• a laser diode array configured to include a plurality of laser diodes, each of which has a different output wavelength;
• a multiplexer configured to receive an optical wave having a wavelength selected among optical waves, each of which has a different wavelength, from the laser diode array through each optical waveguide and transmit the received optical wave to one optical waveguide;
• an optical modulator configured to be integrated on the same PIC chip as the laser diode array and the multiplexer and modulate the optical wave into a specific optical signal;
• an optical switch configured to selectively transmit and receive the optical signal modulated through the optical modulator with a specific output port of an optical phased array;
• a tunable TRx antenna array configured to constitute the optical phased array and radiate the optical signal incident to any optical phased array through the optical switch to the free space;
• and
• a photodetector configured to convert an Rx optical signal received by a Tx optical signal transmitted via the tunable TRx antenna array into an electrical signal.
