  • VERTICAL CAVITY SURFACE EMITTING DEVICES INCORPORATING WAFER FUSED REFLECTORS
    Publication number: 20120134381
    Abstract: A method of forming an optoelectronic device comprising growing a first multi-layer 2 representing a reflector on a first substrate and a second multilayer 4 representing an active region on a second substrate, the first and second substrates being lattice mismatched, fusing the first multi-layer 2 to a third substrate 3, wherein the material of the third substrate 3 is lattice matched with respect to the material of the second multi-layer 4, removing the first substrate to expose the first multi-layer 2, and fusing the first multi-layer to the second multi-layer 4.
