    Abstract: A coherent optical communication system is disclosed comprising, a first transceiver, a second transceiver, and an optical transport medium coupling the first transceiver with the second transceiver. The first transceiver is configured to (i) receive a laser signal from a master laser source as at least one phase synchronized pair of coherent tones, and (ii) modulate data onto a first tone of the at least one phase synchronized pair of coherent tones for transport as a first data signal to the second transceiver over the optical transport medium. It is also configured to (iii) transmit a second tone of the at least one phase synchronized pair of coherent tones over the optical transport medium as an unmodulated first local oscillator signal to the second transceiver.

    Abstract: An optical network communication system utilizes a passive optical network including an optical hub having an optical line terminal, downstream transmitter, an upstream receiver, a processor, and a multiplexer. The upstream receiver includes a plurality of TWDMA upstream subreceivers. The system includes a power splitter for dividing a coherent optical signal from the optical hub into a plurality of downstream wavelength signals, a long fiber to carry the coherent optical signal between the optical hub and the power splitter, and a plurality of serving groups. Each serving group includes a plurality of optical network units configured to (i) receive at least one downstream wavelength signal, and (ii) transmit at least one upstream wavelength signal. The system includes a plurality of short fibers to carry the downstream and upstream wavelength signals between the power splitter and the optical network units, respectively. Each upstream subreceiver receives a respective upstream wavelength signal.

    Abstract: An injection locked transmitter for an optical communication network includes a master seed laser source input substantially confined to a single longitudinal mode, an input data stream, and a laser injected modulator including at least one slave laser having a resonator frequency that is injection locked to a frequency of the single longitudinal mode of the master seed laser source. The laser injected modulator is configured to receive the master seed laser source input and the input data stream, and output a laser modulated data stream.

    Abstract: An optical network communication system utilizes a coherent passive optical network (PON). The system includes an optical line terminal (OLT) having a downstream transmitter and an upstream receiver system configured for time-wavelength division coherent detection. The system further includes a splitter in operable communication with the OLT, and a plurality of optical network units (ONUs) in operable communication with the splitter. Each of the plurality of ONUs is configured to (i) receive downstream coherent burst signals from the OLT, and (ii) transmit at least one upstream burst signal to the OLT. The upstream receiver system further includes a power control module and a local oscillator (LO) configured to generate an optical LO signal The power control module is configured to adaptively control, in real-time, a power level of the optical LO signal.
