Abstract
The reflectivity of absorbing Bragg reflectors consisting of a GaAs/AlAs Br agg mirror and a InGaAs/InGaAsP multiple-quantum-well cavity layer was stud ied as a function of temperature. An absorption dip in the stop band due to the optical confinement of the Fabry-Perot resonance was observed in the r eflectivity spectra. The absorption intensity of the dip increased with tem perature and was explained by the resonant coincidence of the Fabry-Perot c avity mode and the quantum-well absorption. The temperature-dependent refle ctivity spectra were successfully reproduced using the transfer matrix meth od and the linear dependence of the refractive index on temperature.
