Abstract

We describe a frequency-stabilized, polarization-maintained erbium fiber ring laser and its application to coherent communication. The laser frequency is stabilized by using an acetylene (C₂H₂) absorption line and the frequency stability reached as high as 1.3 × 10^-11 for an integration time of 1 s. The output beam of this frequency-stabilized laser has no frequency modulation with a narrow linewidth of 4 kHz. Using this coherent laser and an optical phase-locked-loop (OPLL) technique, we succeeded in a 20 Msymbol/s coherent quadrature amplitude modulation (QAM) transmission over 525 km.
