Abstract

A SOA-based multiwavelength fiber ring laser for fiber sensing network is introduced in the paper.  According to the demand of our sensing network which is a six-channel WDM system, the output wavelength of our MFRL is in the band of 1537nm to 1547nm with a frequency space of 200GHz. In the experiments, stable output and good flatness are acquired. Factors that can influence the wavelength shift of the laser output are also discussed and demonstrated.
