We present wafer bonding techniques applied for the first time in integrating GaAs-based distributed Bragg reflectors (DBRs) with InP-based active regions in optically pumped semiconductor disk lasers. The bonding procedures are performed at a modest temperature of 200 °C and enable multi-watt output powers from 1.3 μm semiconductor disk lasers. These technologies are critical for vertical-cavity lasers emitting in the range 1.3-1.6 μm since monolithically grown lattice-matched InP structures… CONTINUE READING
