Abstract

The thermal dependence of mirror reflective properties in oxide-confined VCSEL is investigated. The temperature distribution over the cavity versus applied current is calculated. The refractive indexes of the mirror layers are redefined by using the temperature coefficients, and changes in radial reflectance spectra of the mirror are analyzed. Results show a shift of stopband DBR at different injection currents and the formation of the temperature lens in the mirror due to decreasing the temperature close to edge of oxide windows
