Wafer bonded 1.55 μm vertical-cavity lasers with continuous-wave operation up to 105 °C

Abstract
We report 105 °C continuous-wave, electrically pumped operation of a 1526 nm vertical-cavity surface-emitting laser. An InP/InGaAsP active region was wafer bonded to GaAs/AlGaAs mirrors, with a superlattice barrier to reduce the number of nonradiative recombination centers in the bonded active region.
