L-band multiwavelength erbium-doped fiber ring laser for sensing applications

Abstract: In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in L-band is proposed and experimentally demonstrated. This spectral region presents some advantages for the detection of dangerous gases. The sensor system presented here is based on ring resonators, and employs fiber Bragg gratings to select the operation wavelengths. The stable SLM operation is guaranteed when all the lasing channels present similar output powers. It is also experimentally demonstrated that when a SLM behavior is achieved, lower output power fluctuations are obtained.
