Abstract:
A light guide apparatus that can redirect light impinging on the apparatus over a wide range of incident angles and can concentrate light without using a tracking system and methods for fabrication. This apparatus uses conditions of total internal reflection and refraction near the critical angle for total internal reflection (near TIR) in order to trap light within the apparatus.
