Abstract :
We have combined the technologies of wafer bonding and micromachining to produce a tunable LED at 1.51 /spl mu/m. The bonding technique allows us to combine an InP-based multiple quantum well structure with a GaAs-based Bragg mirror for higher reflectivity than traditional InP-based mirrors. Micromachining techniques then allow us to suspend a mirror above the surface of the substrate to provide a tuning method for the LED.
