Effects of spatial hole burning on polarization dynamics in edge-emitting and vertical-cavity surface-emitting laser diodes

The dynamical evolution of polarization states in vertical-cavity surface-emitting lasers (VCSELs) and ridge-waveguide edge-emitting laser diodes (RWEELD) has been studied, taking into account the interplay between the mode structure and the gain medium. The role of spatial hole burning in determining polarization switching properties of both device geometries is demonstrated.
