Regular oscillation in two-section laser structures based on /spl delta/-doped superlattices

Abstract

It is theoretically shown that in two-section laser structures based on /spl delta/-doped superlattices a broadened spectral tuning is realised under special requirements for the parameters and excitation conditions in the gain and absorbing sections. The tuning occurs in the stationary operation, during transient process, and regular pulsation regime as well. In the GaAs /spl delta/-doped superlattice lasers, the tuning range covers of up to 60 nm in near infra-red.
