Abstract

We demonstrate a comprehensive multi-dimensional DBR laser simulation. The DBR laser under investigation consists of three longitudinally integrated waveguide sections: an active section providing the optical gain for the laser operation, a passive phase shift section which contains neither gratings nor active material and a DBR mirror section. This structure is representative for longitudinally integrated devices such as widely tunable sampled-grating laser diodes. In our physics-based approach, we solve the fully coupled semiconductor drift-diffusion equations for electrons and holes and the temperature diffusion equation, taking into account longitudinal current and heat flux. Gain calculation and the photon rate equation are included self-consistently. A general and comprehensive solution of the transverse optical field is combined with the longitudinal field distribution including general DBR sections. The simulator is applied for the design and optimization of state-of-the-art tunable lasers. It proofs to be an effective tool for bandgap engineering, for the optimization of the transverse confinement of the optical mode as well as the current, and for thermal management.
