Optical phase‐sensitive amplification of higher‐order QAM signal with single Mach–Zehnder amplitude modulator

Optical phase‐sensitive amplification of higher‐order QAM signal with single Mach–Zehnder amplitude modulator

Abstract An optical phase‐sensitive amplifier (PSA) has the potential of low‐noise optical amplification. A frequency non‐degenerate PSA (ND‐PSA) can amplify arbitrary modulation formats including higher‐order QAM. The ND‐PSA requires a co‐propagating phase conjugated light (idler light) that has be...
