Using a C-band reflective semiconductor optical amplifier and linear cavity laser scheme for L-band multi-wavelength lasing

Abstract

In this demonstration, we first propose and experimentally investigate an L-band multi-wavelength source only using a C-band reflective semiconductor optical amplifier (RSOA) and a linear cavity formed by a fiber coupler, a polarization controller and a reflected fiber mirror. According to the proposed laser structure, two to seven wavelengths can be generated simultaneously in the L-band when the RSOA is operated at different bias currents. Moreover, the stability performances of output power and lasing wavelength are also discussed.
