Abstract :
Summary form only given.One of the most promising techniques for expanding the bandwidth of WDM systems is the L-C band silica-based EDFA in which the signals are split and passed through a parallel configuration, including a conventional EDFA (C-band) for signals ranging from /spl sim/1530 to /spl sim/1565 nm, and an L-band EDFA for signals ranging from /spl sim/1565 to /spl sim/1600 nm. We report a method and demonstration for a spectrally-efficient L-C band EDFA that utilizes the entire wavelength range covering the complete set of L and C bands, by using sampled fiber Bragg grating (FBG) having reflection resonances throughout the L and C bands to efficiently separate the two bands.
