Abstract
A vertical resonator structure with active layer and Bragg reflectors formed in a mesa and provided with an upper contact and a substrate contact. A bond pad for connection to a housing and the upper contact are parts of the same metallization layer that are directly adjacent to one another. For bundling current in the active layer, an aperture can be formed between oxidized regions of an AlGaAs layer. The oxidized regions have at least the dimensions of the bond pad which are for example, 90 &mgr;m and at least approximately 50 &mgr;m.
