Multi-physics simulations of vertical-cavity surface-emitting lasers (VCSELs)
To properly simulate such devices it is required to analyse them from the optical standpoint, from the electronic transport standpoint (drift-diffusion of electrons and holes) and from the thermal standpoint self-consistently. Furthermore, as technology advances, the tendency is to go towards lasers that are more and more nanostructured, thus non-negligible quantum effects can play a key role, to be included in the simulations and hardly treatable within commercial tools in a simple way.
All of these aspects, based on different physical mechanisms and on different spatial scales, represent a challenging task from the simulating point of view, which is one of the goals of our research group.
