Abstract:
1. A vertical surface-emitting optoelectronic device including a buried current-directing aperture, comprising: an active layer including an active region for emitting light, the active region including a nitride; an electrically resistive aperture layer formed over the active region, the electrically resistive layer defining an aperture therein, at least a portion of the electrically resistive layer comprising amorphous aluminum nitride disposed over said active layer and at least a portion of the electrically resistive layer comprising crystallized aluminum nitride disposed over said amorphous aluminum nitride; and, a second crystalline layer that includes nitride formed over said resistive aperture layer, the second crystalline layer doped to be electrically conductive, at least a portion of the second crystalline layer filling in the aperture in the electrically resistive layer, the second crystalline layer in combination with the electrically resistive aperture layer to direct current into a select active region in the active layer to generate light.
