Abstract

The influence of microscopic non-equilibrium dynamics on vertical external-cavity surface-emitting lasers (VECSELs) is investigated through a systematic numerical study of single- and dual-wavelength operation. In single-wavelength operation the microscopic dynamics can be adiabatically eliminated, however in dual-wavelength operation the microscopic dynamics varies with the spectral location of the modes. The optically active quantum wells (QWs) are modeled microscopically using the Semiconductor Bloch equations while the CW laser field is simulated using Maxwell's equations. Higher order correlation terms, such as carrier scattering and polarization dephasing, are treated on the level of second Born-Markov or as effective rates. Results are presented on the modeling, stability, and non-equilibrium effects in dual-wavelength operation.
