Abstract

We report two novel optical injection-locking configurations of DFB laser without high-frequency modulator for probe Stokes signal generation in distributed fiber optical Brillouin sensing. The first one based on injection locking on ring Brillouin laser radiation and second one on self-injection locking on Brillouin amplified radiation. Locking on Brillouin amplified radiation exhibits properties inherent in two phenomena, self-injection locking and injection locking in master-slave configuration at the same time and provides significantly more intensity-stable Stokes signal.
