A detailed threshold simulation of a room-temperature operation of possible GaN/AlGaN/AlN vertical-cavity surface-emitting lasers (VCSELs) is developed in an analytical form to compare usabilities of their various designs. Multiple-quantum-wen VCSEL configurations are proved to be the best suited for this application. Their optimal number of quantum wells is found to be proportional to all optical...
In the present paper, recent results of computer simulations of two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs), transverse modes in gain-guided VCSELs as well as double-heterostructure and quantum-well nitride VCSELs are presented. As expected, the simulations enable us to propose essential design modifications of the devices under consideration.
