Output characterization of a frequency-shifted feedback laser using an SOA as gain medium

摘要

We report the oscillation characteristics of a frequency-shifted feedback laser using a semiconductor optical amplifier (SOA) as gain medium in a fiber ring cavity. The laser was observed to oscillate in multiple wavelengths each of them consisting of a comb of linearly chirped frequencies. The chirp rate was higher than 3PHz/s. Distance measurement resolutions better than 5 mm were obtained.
