Abstract
This paper reports the simulation of L-band multi-wavelength Brillouin–erbium fiber laser that utilizes delay interferometer as a comb filter. The simulation is performed using OptiSystem. The structure exhibits threshold power in terms of Erbium doped fiber amplifier (EDFA) gain of 10[Formula: see text]mW at a very low Brillouin pump power of 0.00316[Formula: see text]mW for the generation of first Stokes. Thirty one output channels were produced with minimum EDFA gain of 1[Formula: see text]W at Brillouin pump power of 0.00316[Formula: see text]mW. In line with theory, it has been observed that higher Brillouin pump power requires low threshold gain and vice versa to generate the Brillouin Stokes.
