Abstract:
A method of fabricating a vertical cavity surface emitting laser comprising the steps of:providing a first DBR mirror structure having positioned on an uppermost surface a bonding layer;providing an active laser structure including a supporting substrate, an etch stop layer, a buffer layer, a p-doped contact layer, a p-doped cladding region, an active region and a n-doped cladding region;mounting the first DBR mirror structure to the active laser structure using wafer bonding techniques, the bonding layer of the first DBR mirror structure being wafer bonded to the n-doped cladding region of the active laser structure;selectively removing from the active laser structure the supporting substrate, the etch stop layer, and the buffer layer; andproviding a second DBR mirror structure on the p-doped contact layer.
