| Abstract(in English) | Optical phase-sensitive amplifiers (PSAs) are promising as optical amplifier repeaters in fiber transmission system, because it has been shown theoretically that these have very low noise figures and waveform reshaping effect of chirped pulses. To realize in-line PSAs, the PSA requires internal light source generating pump light whose optical phase is locked to that of input signal light. The extended-ring cavity semiconductor laser with capability of frequency modulation and narrow linewidth-oscillation is developed as pump source and its optical phase is locked by two methods, optical signal injection and optical phase lock loop. By incorporating with degenerated parametric amplification in nonlinear fiber sagnac interferometer, in-line PSAs with internal phase-locked pump light source is successfully demonstrated. |
