Dispersion managed SOA fiber ring laser for a switching-wavelength pulse source

Abstract

The generation of a time and wavelength-interleaved pulse train from a fiber ring laser incorporated with a semiconductor optical amplifier (SOA) was studied. The laser switches at 4 GHz among 4 wavelength components with less than 1.1 dB variation in the optical power. It was found that the multi-wavelength pulse train generated from a fiber laser is of great importance in WDM communications and photonic ADCs.
