Abstract :
In this paper, semiconductor optical amplifier (SOA)- and dispersion shifted fibre (DSF)-based conjugators are compared using identical fiber-grating-based filter networks and l0-Gbit/s nonreturn-to-zero (NRZ) intensity-modulated data. We believe we report for the first time the use of fiber gratings for efficient ASE filtering and signal extraction. We identify ASE from the amplifiers, rather than the conjugation efficiency, as the limitation to phase conjugation in both approaches
