OPTOELECTRONIC WAVEGUIDES AND METHODS OF MAKING THE SAME

摘要

An optical waveguide may include a graded refractive index structure including a core structure, and a cladding at least partially surrounding the core structure and having an outer surface and an inner surface contacting the core structure. The core structure of the optical waveguide may have a higher refractive index than the cladding. The cladding may have a decreasing refractive index from the inner surface toward the outer surface. Optoelectronic devices that includes the optical waveguide, and methods of making the optical waveguide are also provided.
