Abstract :
We propose a novel digital coherent receiver, where frequency subbands of an ultrafast optical signal are detected in parallel and synthesized with DSP. A proof-of-concept experiment performing two-subband decomposition and reconstruction for PSK signals proves effectiveness of the proposed scheme.
