Numerical and experimental studies of a distributed Bragg reflector laser

Abstract

We report in this paper theoretical and experimental results on the dynamical properties of a distributed Bragg reflector (DBR) semiconductor lasers. Using the traveling wave equation model, we show that a proper choice of coupling coefficient and front facet reflectivity allows an optimization of the laser operation, such that for a wide range of currents injected into the active region the laser emits a continuous-wave beam. The numerical results are in a qualitative agreement with measured characteristics.
