Abstract

Phase effects in AlGaAs/GaAs quantum-well curved-grating distributed feedback (c-DFB) lasers with focused output radiation has been theoretically studied. The results of analysis are compared to experimental data available for the analogous curved-grating distributed Bragg reflector (c-DBR) lasers. It is shown that allowance for the indicated phase effects in the design of a c-DFB laser resonator is of key importance in ensuring the perfect spectral and spatial characteristics of the output radiation of such lasers.
