Abstract: An optical transmitter may include a transmit laser assembly configured to emit multiple light beams. The optical transmitter may additionally include an isolator configured to rotate a corresponding polarization state of each of the multiple light beams. The optical transmitter may additionally include a power multiplexing combiner configured to receive the multiple light beams from the isolator and combine the multiple light beams into a combined light beam. The optical transmitter may additionally include a lens configured to focus the combined light beam onto an optical fiber for transmission.

Abstract: In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.

Abstract: A system may include a first light source configured to generate a first beam of light at a first wavelength; a second light source configured to generate a second beam of light at a second wavelength; a third light source configured to generate a third beam of light at a third wavelength; and a fourth light source configured to generate a fourth beam of light at a fourth wavelength. The system may also include a thin-film filter, a first polarization beam splitter (PBS), a wave plate and a second PBS. The thin-film filter, the first PBS, the wave plate, and the second PBS may be configured to combine the first beam, the second beam, the third beam and the fourth beam into a combined beam of light.
