Optical signal receiver photonic integrated circuit (RxPIC), an associated optical signal transmitter photonic integrated circuit (TxPIC) and an optical network transmission system utilizing these circuits

摘要: A photonic integrated circuits (PICs), also referred to as opto-electronic (OEICs), and more particularly a PIC in the form of an optical receiver or RxPIC for use transport networks. Also, transmitter (TxPIC) is disclosed conjunction with network. The chip cast from InP wafer made Group III-V elemental materials InGaAsP/InP regime fabrication accomplished through selective metalorganic vapor phase epitaxy (MOVPE) known chemical deposition (MOCVD). Integrated on chip, starting at input end which coupled receive multiplexed data signals network amplifier, demultiplexer, plurality on-chip photodiodes (PDs) each demultiplexed signal AWG DEMUX optical-to-electrical conversion. amplifier may be gain clamped semiconductor (GC-SOA) off-chip fiber amplifier. optional if channel demultiplexer provides minimal insertion loss optimum properly designed arrayed waveguide grating (AWG) demultiplexer.
