摘要： Incandescent lighting structure. The structure includes a thermal emitter that can, but does not have to, include a first photonic crystal on its surface to tailor thermal emission coupled to, in a high-view-factor geometry, a second photonic filter selected to reflect infrared radiation back to the emitter while passing visible light. This structure is highly efficient as compared to standard incandescent light bulbs.

摘要： The present invention provides systems, articles, and methods for discriminating electromagnetic radiation based upon the angle of incidence of the electromagnetic radiation. In some cases, the materials and systems described herein can be capable of inhibiting reflection of electromagnetic radiation (e.g., the materials and systems can be capable of transmitting and/or absorbing electromagnetic radiation) within a given range of angles of incidence at a first incident surface, while substantially reflecting electromagnetic radiation outside the range of angles of incidence at a second incident surface (which can be the same as or different from the first incident surface). A photonic material comprising a plurality of periodically occurring separate domains can be used, in some cases, to selectively transmit and/or selectively absorb one portion of incoming electromagnetic radiation while reflecting another portion of incoming electromagnetic radiation, based upon the angle of incidence. In some embodiments, one domain of the photonic material can include an isotropic dielectric function, while another domain of the photonic material can include an anisotropic dielectric function. In some instances, one domain of the photonic material can include an isotropic magnetic permeability, while another domain of the photonic material can include an anisotropic magnetic permeability. In some embodiments, non-photonic materials (e.g., materials with relatively large scale features) can be used to selectively absorb incoming electromagnetic radiation based on angle of incidence.

摘要： A filter to transmit incident radiation at a predetermined incidence angle includes a plurality of photonic crystal structures disposed substantially along a surface normal direction of the filter. The photonic crystal structure includes a multilayer cell that comprises a first layer having a first dielectric permittivity, and a second layer having a second dielectric permittivity different from the first dielectric permittivity. The first layer and the second layer define a Brewster angle substantially equal to the predetermined incidence angle based on the first dielectric permittivity and the second permittivity. Each photonic crystal structure in the plurality of photonic crystal structures defines a respective bandgap, and the respective bandgaps of the plurality of photonic crystal structures, taken together, cover a continuous spectral region of about 50 nm to about 100 mm.

摘要： An apparatus for generating electricity via thermophotovoltaic (TPV) energy conversion includes a metallic combustor to convert fuel into heat. The apparatus also includes a metallic photonic crystal to emit electromagnetic radiation within a predetermined wavelength band in response to receiving the heat from the combustor. A brazing layer is disposed between the combustor and the photonic crystal to couple the combustor with the photonic crystal. The apparatus also includes a photovoltaic cell, in electromagnetic communication with the photonic crystal, to convert the electromagnetic radiation emitted by the photonic crystal into electricity.

摘要： A thermal emitter device includes a cavity structure that comprises an active medium for allowing thermal emissions to occur. A photonic crystal structure is positioned on one side of the cavity structure. The photonic crystal structure comprises alternating layers of high index and low index materials and acts as a first mirror for the cavity structure. A highly reflective mirror structure is positioned on another side of the cavity structure and acting as both the high-temperature source of radiation and a second mirror for the cavity structure.
