Paper Abstract

We have described a frequency-stabilized, polarization-maintained erbium fiber ring laser. This laser has no frequency modulation at the output beam. A tunable single-mode laser has also been newly developed by simultaneously controlling a tunable FBG with a 1.5 GHz bandwidth and a PZT in the cavity. The frequency stability reached as high as 1.3 x 10-11 for an integration time of 1 s and the linewidth was as narrow as 4 kHz. Using this coherent laser as a light source, we successfully transmitted a 20 Msymbol/s coherent quadrature amplitude modulation (QAM) signal over 525 km and achieved error free transmission.
