Abstract
An optical concentration/diffusion apparatus and method is provided that uses a waveguide having a graded index of refraction in a first direction. Light propagating in a second direction different from the first direction follows a curved, path being reflected at multiple intervals by a planar interface of the waveguide. Reflectors are located along the planar interface at a spacing that is selected to limit their interaction with the light propagating in the second direction. Coupling elements are located in optical communication with the reflectors. When used as a concentrator, light is focused by the elements onto the reflectors and redirected in the second direction towards one or more exit apertures. When used as a diffuser, light in the second direction is redirected by the reflectors toward the elements and diffused at multiple exit apertures.
