    摘要： A phase-shift keyed signal demodulator and method for demodulating is disclosed. An example demodulator includes N filters that receive inputs from a splitter and include transmission functions offset from one another. N pairs of photodiodes receive the transmitted and reflected beams from each filter and a decoder converts the outputs of the pairs of photodiodes to one or more data symbols.

    摘要： An optical transmitter with chirp control includes an input polarizer having an input that receives an optical signal. The input polarizer polarizes the optical signal along an input polarization axis. A Mach-Zehnder modulator includes an optical input that is coupled to an output of the input polarizer and an electrical input that receives a modulation signal. The Mach-Zehnder modulator modulates the optical signal with the modulation signal. The input polarization axis of the input polarizer is chosen to achieve a desired chirp of the modulated optical signal. An output polarizer is coupled to the output of the Mach-Zehnder modulator. The output polarizer polarizes the modulated optical signal along a desired output polarization axis that combines TE and TM mode polarizations.

    摘要： A phase-shift keyed signal demodulator is disclosed including a filter positioned to receive an input beam, a first photodiode positioned to receive light reflected from the filter, and a second photodiode positioned to receive light transmitted through the filter. A difference between outputs of the first and second photodiodes is interpreted to determine a data value encoded in the input beam. In another embodiment N filters receive inputs from a splitter and include transmission functions offset from one another. N pairs of photo diodes receive the transmitted and reflected beams from each filter and a decoder converts the outputs of the pairs of photodiodes to one or more data symbols.
