Abstract
Semiconductor lasers with third-order waveguide mode emission are a promising route toward compact twin-photon sources. In these structures, emission on the third-order mode is required for satisfaction of the phase-matching condition between the pumping frequency and fundamental modes at half frequency and so the production of twin photons. Phase matching depends critically on sample temperature through the dependence of the effective refractive indices of the sample. The dependence of laser mode emission on the temperature of a semiconductor structure specially designed for third-order mode emission at 775 nm is studied. It is shown that the third-order mode emission is preserved up to 40 °C whereas a contribution from other modes becomes significant above that temperature.
