Abstract: An method for stabilized photonic transmission is described. A light source of limited coherence length is wavelength shifted, stabilized, and data encoded to provide a stabilized photonic signal. A modulation synthesizer provides a modulation waveform embedded with the shifting, stabilization and data encoding mechanisms. A variety of modulation techniques are supported. The modulation waveform is optimized for the particular modulation technique. A wavelength error detector provides feedback to the modulation synthesizer. The error signal is used to stabilize the photonic signal and correct channel wavelength errors. Fixed wavelength channels and spread spectrum channels are supported.

Abstract: An apparatus for photonic transceiving spectrally replicates a photonic input signal to provide a replicated photonic signal. The replicated photonic signal contains multiple copies of the photonic input signal shifted to various wavelengths. The replicated photonic signal is then filtered to provide a photonic output signal within a desired passband. The photonic input signal may be spectrally replicated through a variety of mechanisms including four-wave mixing, modulation via a harmonically rich modulation waveform, recursive wavelength shifting and complementary recursive wavelength shifting.

Abstract: An apparatus for photonic wavelength shifting and stabilization is described. The apparatus receives a photonic signal, comprised of one or more channels, and provides a wavelength shifted, stabilized, and channelized photonic signal. Data encoding is also supported. A modulation synthesizer provides a modulation waveform embedded with the shifting, stabilization and data encoding mechanisms. A variety of modulation devices are supported. The modulation waveform is optimized for the particular modulation device. A wavelength error detector provides feedback to the modulation synthesizer. The error signal is used to stabilize the photonic signal and correct channel wavelength errors. Fixed wavelength channels and spread spectrum channels are supported.
