Electrical-thermal-optical simulation of GaAs/AlGaAs oxide-confined VCSELs

Abstract

A three-dimensional electrical-thermal-optical numerical solver is applied to model top-emitting oxide-confined verticalcavity surface-emitting lasers (VCSELs) with GaAs/AlGaAs multiple-quantum-well active region. CW mode of operation is simulated over a range of voltages, covering sub-threshold spontaneous emission and lasing emission. Effect of selfdistribution of electrical current is demonstrated for the first time in a self-consistent electrical-thermal-optical simulation of VCSELs.
