ABSTRACT:
An optical coupler is provided that comprises a single lens component, comprising two axially-graded index of refraction elements, each having a low refractive index surface and a high refractive index surface and joined along their respective high refractive index surfaces. As configured, the optical coupler is useful as a solar concentrator for concentrating solar radiation onto a solar cell or other solar-receptive medium.
