摘要
A system and method for channelization of a wideband radio frequency signal into multiple narrowband channels includes obtaining, a dual-banded optical signal, where the dual-banded signal is a translated wideband radio frequency signal, and where the dual-banded signal includes a signal and an idler. The method also includes modifying, by the spectral phase mask, the spectral phases of at least one of the signal or the idler, where the modifying produces a spectral phase modulated output comprising at least one of a spectrally-modulated signal or a spectrally modulated idler. The method includes outputting, by the spectral phase mask, the spectral phase modulated output to an optical phase sensitive amplifier. The method includes receiving, by the optical phase sensitive amplifier, the spectral phase modulated output, and either amplifying or de-amplifying, by the optical phase sensitive amplifier, each component of the spectrally modulated output.
