Abstract:
1. A solar energy apparatus comprising: a carrier; a waveguide, disposed on the carrier, the waveguide having a top surface, a bottom surface, a collection end, and a detection end; one or more scattering features disposed on the top surface of or within the waveguide, the scattering features extending from the collection end to the detection end, and operating with the waveguide in a leaky propagation mode to receive energy within a solar wavelength region; wherein the scattering features further comprise one or more metallic structures located on or within the waveguide; wherein the width of a selected scattering feature decreases monotonically with respective position of the selected scattering feature from the collection end to the detection end; and a solar detector, disposed adjacent the detection end.
