Modeling the Lamb mode-coupling constant of quantum well semiconductor lasers

Modeling bidirectionally coupled single-mode semiconductor lasers

We develop a dynamical model suitable for the description of two mutually coupled semiconductor lasers in a face-to-face configuration. Our study considers the propagation of the electric field along the compound system as well as the evolution of the carrier densities within each semiconductor laser. Mutual injection, passive optical feedback, and multiple reflections are accounted for in this...

A Comparison of Amplitude-Phase Coupling and Linewidth Enhancement in Semiconductor Quantum- Well and Bulk Lasers

The amplitude-phase coupling factor a (linewidth enhancement factor) is compared in typical semiconductor quantum-well and bulk double heterostructure lasers. As a direct consequence of the reduction of the differential gain, there is no reduction of a in the single quantum-well lasers compared to the bulk lasers. The number of quantum wells strongly affects the amplitude-phase coupling in quan...

Modeling and Simulation of Strained Quantum Wells in Semiconductor Lasers

Amodel allowing for efficiently obtaining band structure information on semiconductor Quantum Well structures will be demonstrated which is based on matrix-valued kp-Schrödinger operators. Effects such as confinement, band mixing, spin-orbit interaction and strain can be treated consistently. The impact of prominent Coulomb effects can be calculated by including the Hartree interaction via the ...
