ABSTRACT:
A light-receiving device including an optical waveguide for propagating a time-series signal light pulse string, a plurality of optical gates arranged in series along the optical waveguide and capable of switching between a transparent mode and a light-receiving mode in accordance with the presence/absence of a trigger light pulse, a mode switching unit for switching each of the optical gates from the transparent mode to the light-receiving mode by sending the trigger light pulse to each of the optical gates such that each of the optical gates can receive a predetermined slot included in the signal light pulse string, and a read circuit for reading the slots received by the plurality of optical gates as parallel electrical signals. The light-receiving device allows for efficient optoelectronic demultiplexing as compared to optical demultiplexing using optical time-division multiplexing (TDM) while achieving a compact, lightweight, and stable arrangement and a low dependency on polarization.
