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...
