Numerical analysis of semiconductor ring lasers with backscattering coefficients mismatch

Abstract

In order to account for the asymmetry along the ring, the numerical analysis of a semiconductor ring laser using the basic two-mode model and a parameter mismatch in the backscattering coefficients is presented in this paper. The operation of the laser is discovered to be affected by changing the conservative backscattering parameter for a fixed value of the dissipative backscattering parameter, and the bidirectional regime with alternating oscillation can be suppressed. A good correspondence between the numerical results of this paper and the experimental results of the literature is obtained.
