Abstract:
1. An optical device capable of emitting electromagnetic radiation at a wavelength of at least about 365 nanometers comprising: a gallium and nitrogen containing substrate having a surface, wherein the surface is characterized by a semipolar crystallographic orientation; an n-type semipolar gallium and nitrogen containing layer overlying the surface; a dielectric material layer overlying the n-type semipolar gallium and nitrogen containing layer, wherein the dielectric material layer defines one or more growth regions, wherein the one or more growth regions is characterized by a maximum dimension no larger than ten microns; an n-type semipolar gallium and nitrogen containing material overlying each of the one or more growth regions; and a light emitting active region overlying the n-type semipolar gallium and nitrogen containing material overlying at least one of the one or more growth regions, wherein the light emitting active region comprises a semipolar gallium, nitrogen, and indium containing material, and wherein the light emitting active region is characterized by an indium mole fraction from about 20% to about 60%.
