Abstract:
A tapered core waveguide which may be configured as a spectral component splitter, a spectral component combiner, and various combinations thereof including a reflective mode of operation. The tapered core waveguide has an aperture and cladding, and is dimensioned such that radiant energy admitted into the core via the aperture and having at least two spectral components would be emitted via the cladding at a location dependent on its frequency and/or its polarization, and that a plurality of spectral components injected to the core via the cladding will be mixed and emitted via the aperture.
Abstract:
Methods for creating Continuous Resonant Trap Refractors (CRTR's), and methods for creating stratum structure in which the CRTR is to be disposed, are disclosed The invention further include novel methods for patterning an etch mask, and forming collimators of adjustable length.
Abstract:
A layered waveguide stack radiant energy converter array having a plurality of superposed waveguides, each waveguide having a core layer having a radiant energy converter disposed therein, and two cladding layers disposed on opposing sides of the core. In some embodiments the conductive layers are electrically coupled to the converter and act as charge carriers for it, and in other wires are provided for individual converters. Each waveguide has at least one inlet for passage of radiant energy therethrough, the inlet extending between the cladding layers, such that radiant energy entering the waveguide impinges on at least two layers of the waveguide, the inlet further defining a minimum cutoff frequency for the energy to propagate in the waveguide. In some embodiments such as solar panels, energy is harvested. In other embodiments energy is detected such as for example is done in a camera focal plane sensor. In some embodiments the stack is used to emit light.
