Construction of the refractive index profiles for few-mode planar optical waveguides

Optical waveguide loss minimized into gallium nitride based structures grown by metal organic vapor phase epitaxy

“…1 With technology becoming more and more mature, there is a large demand for designing and analyzing optical waveguides to function as a basic building block for integrated optical circuits. 2,3 While optical waveguide technology is somewhat mature, and in certain instances well established in other material systems, there has been very little work done on GaN or its alloys in terms of optical waveguide applications. The development of new photonic devices requires the precise knowledge of optical properties such as refractive index, optical losses, electro-optic constants.…”
