Abstract

The maximum tolerable amplitude backreflection coefficient rext,c into a fiber distributed-feedback laser before the onset of instability has been investigated. rext,c was found to decrease with increasing external cavity lengths up to 320 m and to be proportional to the relative linewidth of the relaxation oscillation resonance. The tolerable length of Rayleigh backscattering standard telecom fiber was found to be 135–200  m. An observed degradation in the laser stability and slope efficiency at low pump powers is believed to be due to UV-induced saturable absorbers.
