MULTIWAVELENGTH RING LASERS EMPLOYING SEMICONDUCTOR OPTICAL AMPLIFIERS AS GAIN MEDIA

摘要

Stable simultaneous multiwavelength lasing is demonstrated with a novel fiber-ring laser incorporating a semiconductor optical amplifier. Band-pass comb filtering is constructed in the ring cavity with the combination of a wideband Fabry-Perot comb filter and a bandpass filter. Ten lasing lines with a fixed wavelength spacing of 1.6 nm are implemented and the multiwavelength lasing ranges can be flexibly chosen.
