Abstract
Fiber Bragg gratings (FBG) may be used to perform phase adjustment for optimal phase-sensitive amplification. Specifically, FBGs may be used between the idler stage and the amplification stage of an optical phase-sensitive amplifier for phase shifting or tuning. The phase shifting or tuning may be applied to at least one of an input optical signal, an idler signal, and an optical pump. A feedback control loop may be used in the phase-sensitive optical amplifier with respect to an output optical signal for optimal phase adjustment.
