A discretely tunable erbium-doped fiber ring laser with 273 Ch./spl times/50 GHz-spacing ITU-T grids in C- L-band regions

摘要

We fabricated a wide-band discretely-tunable erbium-doped fiber laser with 50 GHz-spacing ITU-T grids in the C- and L-bands by incorporating a solid Fabry-Perot interferometer(SFPI) and a fiber Fabry-Perot(FFP) tunable filter. This laser was tunable over 111 nm with 273 channels.
