Efficient multi-channel coherent optical system

Abstract:

A coherent optical system includes an optical transmit (Tx) path, a coherent optical receive (Rx) path, and a multi-channel optical path coupled to the optical Tx path and the coherent optical Rx path. The multi-channel optical path includes a number of parallel-connected channels and a formatting optics block having an optical beam directed to a target. Each channel includes an optical amplifier, and the optical Tx path, the coherent Rx path, and the multi-channel optical path are realized as a photonic integrated circuit (PIC).
