Paper Abstract

In this paper we present the systematic numerical studies of nonlinear operation of planar waveguide DBR/DFB lasers with circular grating. An approximate formula relating small signal gain to the output power and the parameters of the structure characteristics for this kind of laser is derived. Laser characteristics obtained revealing gain saturation effects can be used for design optimal structure providing maximal output power for the given pumping rate of the laser medium.
