ABSTRACT:
A laser fabricated from a substrate having top and bottom surfaces. A first stack of mirror layers of alternating different refractive indices are formed upon the substrate top surface. An active layer defining a mesa is formed on top of the first stack of mirror layers. A second stack of alternating different refractive indices mirror layers are formed upon the active layer mesa. A current confinement layer is formed about the side of the active laser mesa. A first contact is formed upon the substrate bottom surface while a second contact is formed upon a portion of said active layer remote from the active layer mesa.
