Abstract
A method 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 with a harmonically rich modulation waveform, recursive wavelength-shifting and complementary recursive wavelength-shifting.
