Abstract

In this work, the simulation of the 980 nm InGaAs intra-cavity-contacted oxide-confined vertical-cavity surface-emitting lasers is presented including the thermal effects. We analyze the thermal, electrical and optical properties of such devices with the different thicknesses of contact layers. Results of simulations show the larger optical power for devices with thicker contact layers. The device with contact layers of 5λ/4n thickness has the maximal modulation bandwidth..
