Abstract :
We analyze the influence of integrated outcoupler, characterized by effective end-reflectivity, on the statistical properties of light generated by circular-grating distributed Bragg reflector laser. In our paper we concentrate on the effects resulting from the nonorthogonality properties of laser modes. The semi classical approach based on stationary and time-dependent solution of the Fokker-Planck equation is used. Numerical results obtained for CG-DBR structure reveal the behavior of statistical parameters of light such as the mean laser intensity, intensity fluctuations and the laser linewidth as a functions of the effective complex reflection of the integrated outcoupler.
