Patent abstract
A surface emitting laser having a substrate with top and bottom surfaces, a first stack of mirror layers of alternating indices of refraction located upon the top surface of the substrate and an active layer disposed over the first stack. The surface emitting layer also includes a second stack of mirror layers of alternating indices of refraction disposed over the active layer and a reduced-diameter mirror extension portion of the second stack that forms an optical aperture of the surface emitting laser extending outwards from a center portion of the second stack on a side of the second stack opposite the active layer.
