Abstract
A quantum wire in a groove in a semiconductor layer emits coherent light in a semiconductor laser structure. Linear array, vertical array and two-dimensional array multiple quantum wire semiconductor laser structures are also embodiments of the quantum wire in a semiconductor layer groove. Optical waveguides and reverse bias junctions can also be formed with the quantum wire semiconductor laser structures.
