Widely tunable erbium-doped fiber ring laser covering both C-bandand L-band

摘要

We demonstrate a widely tunable erbium-doped fiber (EDF) ringnlaser covering both the conventional wavelength band (C-band) and thenlong wavelength band (L-band). It features a wide tunable range, highnoutput power, low-coherent, and depolarized output. A tunable range overn80 nm (1520-1600 nm) has been achieved by optimizing the length of thenEDF and by using an intracavity fiber Fabry-Perot (FFP) filter
