Abstract
In one example, an optical device may include a waveguide having a core index of refraction that decreases along a length of the waveguide and an edge index of refraction of the waveguide that is constant along the length of the waveguide. The central rays of the optical signals travelling through the waveguide may be refracted towards higher radii while the outer rays propagate unaffected. The optical device may decrease dispersion of the optical signals travelling through an optical fiber.
