摘要: Monitoring a bias point of an optical modulator includes receiving an optical signal modulated by the optical modulator. Photons of the optical signal are received at a photon reactive material operable to produce a reaction in response to the arrival of a predetermined number of photons. Reactions are produced in response to the arrival of the photons of the optical signal. Feedback is generated in response to the reactions. The feedback reflects the waveform of the optical signal, and indicates one or more bias points of the optical modulator.

摘要: A system operable to modulate a signal according to phase-shift keying (PSK) modulation includes one or more phase modulators that comprise one or more fractional phase modulators. A fractional phase modulator includes a splitter that splits a communication signal to yield a first communication signal with first amplitude and a second communication signal with second amplitude, where the ratio of the first and second amplitudes correspond to a phase shift. A phase shifter phase shifts the first or second communication signal. A first modulator modulates the first communication signal at a constant phase. A second modulator modulates the second communication signal at phases corresponding to the phase shift to encode data. A coupler couples the first communication signal and the second communication signal.
