Paper Abstract

We designed a distributed Bragg reflector mirror with a double-wavelength reflection, which can be used into opticallypumped vertical external cavity surface emitting lasers. This kind of mirror can reflect both the lasing light as a resonance mirror and the pumping light to reflect the pumping light back into absorbing area for increasing the absorption efficiency and improving the thermal characteristics of the laser device. By using GaAs/AlGaAs heterostructure layers and material data, the optical characteristics of the distributed Bragg reflector mirror with a double wavelength reflection at two peaks was calculated. From the calculated results, the two reflection peaks occur at 808nm and 980nm just as the structure design. The reflectivity can be more than 99% for 25-pair DBR. The reflection band width is about 20nm and 25nm for the 808nm and 980nm peaks respectively. This can give a flexibility selection for the double-wavelength distributed Bragg reflector structure design.
