The use of a curved grating enable the combination of not only of the high-power of a broad stripe device and spectral control provided by a diffraction grating but also the output beam focusing in the plane of p-n-junction. The theoretical investigation of the c-DBR laser providing output beam focusing using the extended (3&3) transfer matrix formalism is presented. Threshold pumping, wavelength and emitted power are derived in good accordance with experimental results. We believe, this method will make possible significant optimization of the parameters of the c-DBR laser comparing to that achieved to date.
