Abstract
A hybrid mirror structure for a visible emitting VCSEL including a first distributed Bragg reflector disposed on a substrate and including first pairs of alternating layers including an oxidized aluminum material and second pairs of alternating layers. A first cladding region disposed on the first distributed Bragg reflector, an active region disposed on the first cladding region, and a second cladding region disposed on the active region, and a second distributed Bragg reflector disposed on the second cladding region. In the first distributed Bragg reflector, each pair of alternating layers includes a layer containing oxidized aluminum. Alternate layers contain AlAs which is oxidized to decrease the index of refraction to a range of approximately 1.3 to 1.7.
