ABSTRACT:
A vertical emission laser structure comprising an active region between stacks of layers forming Bragg reflection mirrors respectively of the n-type and of the p-type, wherein: the stacks of layers are formed by different pairs of materials in the n-type mirror and in the p-type mirror; the pair of materials constituting the n-type mirror comprises materials having a conduction band gap that is narrow or even non-existent; and the pair of materials constituting the p-type mirror comprises materials having a valance band gap that is narrow, or even non-existent.
