Abstract: An energy converter for converting multi-frequency radiant energy into electrical energy is disclosed, comprising a plurality of superposed lateral waveguides having photovoltaic energy transducers disposed within. The waveguide include charge collectors, which may be the cladding. A plurality of spectral refractors termed Continuous Resonant Trap Refractors (CRTR) are disposed within the lateral waveguides the refractors comprising a tapered core waveguide, the wider end of which defining an aperture, and the tapered core width decreasing in magnitude as a function of the depth. A cladding is disposed about the tapered core. The aperture of the tapered core is dimensioned to allow passage of radiant energy comprising at least two frequencies. The varying width of the tapered core will cause different frequencies to reach a state at which they will penetrate the cladding and be emitted from the spectral refractor sorted by depth, and be coupled to respective lateral waveguides and/or transducers.

Abstract: Structures and techniques introduced here enable the design and fabrication of photodetectors (PDs) and/or other electronic circuits using typical semiconductor device manufacturing technologies meanwhile reducing the adverse impacts on PDs' performance. Examples of the various structures and techniques introduced here include, but not limited to, a pre-PD homogeneous wafer bonding technique, a pre-PD heterogeneous wafer bonding technique, a post-PD wafer bonding technique, their combinations, and a number of mirror equipped PD structures. With the introduced structures and techniques, it is possible to implement PDs using typical direct growth material epitaxy technology while reducing the adverse impact of the defect layer at the material interface caused by lattice mismatch.

Abstract: A solar power method is provided using two-stage light concentration to drive concentrating photovoltaic conversion in conjunction with thermal collection. The method concentrates light rays received in a plurality of transverse planes towards a primary linear focus in an axial plane, which is orthogonal to the transverse planes. T band wavelengths of light are transmitted to the primary linear focus. R band wavelengths of light are reflected towards a secondary linear focus in the axial plane, which is parallel to the primary linear focus. The light received at the primary linear focus is translated into thermal energy. The light received at the secondary linear focus is focused by optical elements along a plurality of tertiary linear foci, which are orthogonal to the axial plane. The focused light in each tertiary primary focus is focused into a plurality of receiving areas, and translated into electrical energy.
