ABSTRACT:
Enhanced higher order mode discrimination is obtained in injection lasers with lateral spatial thickness variations (LSTV) in the active layer with (1) the proper refractive index quantitative differences in the cladding layers contiguous with the active layer and (2) by fabricating the active layer to have a rapidity in its LSTV from the maximum thickness to the minimum thickness that is very gradual.
