Abstract:
1. An energy collection system, comprising: an energy collection device; an energy concentration device comprising a planar substrate and a non-periodic, sub-wavelength, dielectric grating disposed on a first surface of the planar substrate, the energy collection device being external to the energy concentration device and at least a portion of the energy collection device being disposed at a second surface of the planar substrate opposite the first surface; and a guided mode resonant waveguide disposed as a layer adjacent to the first surface of the energy concentration device, the energy concentration device being sandwiched between the guided mode resonant waveguide and the energy collection device, wherein the dielectric grating is to couple incident electromagnetic radiation into the planar substrate, the coupled electromagnetic radiation to pass through the planar substrate and into the energy collection device, and wherein the energy concentration device is to receive electromagnetic radiation coupled from the guided mode resonant waveguide by the dielectric grating.
