Abstract: Techniques, systems, devices and materials are disclosed for spectrally selective coatings for optical surfaces having high solar absorptivity, low infrared emissivity, and strong durability at elevated temperatures. In one aspect, a spectrally selective coating includes a substrate formed of a light absorbing material, and a composite material formed over the substrate and including nanoparticles dispersed in a dielectric material, in which the composite material forms a coating capable of absorbing solar energy in a selected spectrum and reflecting the solar energy in another selected spectrum.

Abstract: A spectrometry system may include an etalon array having a first etalon and a second etalon. The first etalon may be configured to process light to at least generate a first transmission pattern. The first transmission pattern may have at least a first transmission peak corresponding to a first wavelength in an original spectrum of the light. The second etalon may be configured to process the light to at least generate a second transmission pattern. The second transmission pattern may have at least a second transmission peak corresponding to a second wavelength in the original spectrum of the light. The first etalon may have a different thickness than the second etalon in order for the first transmission pattern to have at least one transmission peak that is at a different wavelength than the second transmission pattern. The first transmission pattern and the second transmission pattern may enable a reconstruction the original spectrum of the light.

Abstract: A light emitting diode may include a light emission layer and a charge transport layer disposed on the light emission layer. A grating including a plurality of nanoholes may be formed by removing a portion of the charge transport layer and/or the light emission layer and depositing a plasmonic metamaterial on a remaining portion of the charge transport layer and/or the light emission layer. The nanoholes may include the plasmonic metamaterial deposited inside the recesses formed by the remaining portion of the charge transport layer and/or the light emission layer, with an additional portion of the charge transport layer disposed on top. A pitch, diameter, and/or depth of the nanoholes may be configured to maximize the quantum efficiency of the light emitting diode, especially at a microscale of less than 100 microns.

Abstract: In one aspect, there is provided an apparatus including a light emitting diode. The apparatus may include a plurality of layers including a substrate layer, a buffer layer disposed on the substrate layer, a charge transport layer, a light emission layer, another charge transport layer, and/or a metamaterial layer. The other charge transport layer may have at least one channel etched into the other charge transport layer leaving a residual thickness of the other charge transport layer between a bottom of the etched channel and the light emission layer. A metamaterial layer may be contained in the at least one channel that is proximate to the residual thickness of the charge transport layer. The metamaterial may include a structure including at least one of a dielectric or a metal. The metamaterial may cause the light emitting diode to operate at higher frequencies and with higher efficiency.

Abstract: The document discloses transferrable hyperbolic metamaterial particles (THMMP) that display broadband, selective, omnidirectional absorption and can be transferred to secondary substrates, allowing enhanced flexibility and selective transmission. A device having metamaterial nanostructures includes a substrate and metamaterial nanostructures engaged to the substrate to form an optical layer to interact with light incident to the optical layer to exhibit optical reflection or absorption or transmission that is substantially uniform over a spectral range of different optical wavelengths associated with materials and structural features of the metamaterial nanostructures, each metamaterial nanostructure including different material layers that are interleaved to form a multi-layer nanostructure.
