Abstract:
1. An apparatus for receiving energy within a solar wavelength region comprising: a waveguide, having a top surface, a bottom surface, a collection end, and a detection end; a first plurality of scattering features disposed in a first array on the top surface of or within the waveguide, the first array of scattering features positioned in locations extending from the collection end to the detection end, and operating with the waveguide in a leaky propagation mode to receive the energy within a solar wavelength region; and a second plurality of scattering features disposed in a second array on or within the waveguide, the scattering features in the second array each positioned in a location adjacent a corresponding scattering feature of the first array and therefore also positioned in locations extending from the collection end to the detection end, and arranged such that the scattering features of second array are each orthogonally disposed with respect to and spaced laterally apart from a corresponding one of the scattering features of the first array.
