  • Photonics-based channelization enabled by phase-sensitive amplification
    Patent number: 9979484
    Abstract: 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.

  • System for continuously active stabilization of interferometers in quantum time-bin entanglement distribution
    Patent number: 9954623
    Abstract: Provided are methods and systems for controlling a phase characteristic of entangled photon pairs. The phase characteristic may be a relative phase difference between photons of the entangled photon pair. Also provided are methods and systems for stabilizing distributed interferometers used in quantum communication systems.
