SELF-INJECTION OPTICAL TRANSMITTING AND RECEIVING MODULE AND WAVELENGTH DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK SYSTEM

摘要

Embodiments of the present invention provide a self-injection optical transceiver module and a WDM-PON system based on the optical transceiver module. The self-injection optical transceiver module includes a gain medium, a photoelectric converter, at least one arrayed waveguide grating AWG, and a partial reflection mirror. The at least one AWG includes two common ports and multiple branch ports. One of the two common ports functions as a signal sending port, and the other functions as a signal receiving port, where bandwidth of the signal sending port is less than that of the signal receiving port. The gain medium and the photoelectric converter are connected to one of the branch ports of the AWG. The AWG and the partial reflection mirror are configured to cooperatively perform wavelength self-injection locking on an optical signal provided by the gain medium, and output the optical signal through the signal sending port. The AWG is further configured to demultiplex an optical signal received by the signal receiving port to a branch port. Embodiments of the present invention may effectively improve the performance of the self-injection optical transceiver module and the WDM-PON system.
