Abstract
An in-line optical phase-sensitive amplifier with a phase-locked pump source is demonstrated. The pump source, which consists of a modelocked semiconductor ring laser, is phase-locked to the input signal light by optical injection of the signal. The randomly modulated signal pulses are successfully amplified in a Sagnac interferometer-type parametric amplifier pumped by the injection-locked laser
