摘要： A manufacturing method of a photonic crystal is provided. In the method, a high-refractive-index material is conformally deposited on an exposed portion of a periodic template composed of a low-refractive-index material by an atomic layer deposition process so that a difference in refractive indices or dielectric constants between the template and adjacent air becomes greater, which makes it possible to form a three-dimensional photonic crystal having a superior photonic bandgap. Herein, the three-dimensional structure may be prepared by a layer-by-layer method.

摘要： A multi-channel polarized thermal emitter (PTE) is presented. The multi-channel PTE can emit polarized thermal radiation without using a polarizer at normal emergence. The multi-channel PTE consists of two layers of metallic gratings on a monolithic and homogeneous metallic plate. It can be fabricated by a low-cost soft lithography technique called two-polymer microtransfer molding. The spectral positions of the mid-infrared (MIR) radiation peaks can be tuned by changing the periodicity of the gratings and the spectral separation between peaks are tuned by changing the mutual angle between the orientations of the two gratings.

摘要： A metallic photonic crystal (MPC) structure used as a filter with incandescent lighting is presented that significantly improves efficiency, while retaining the desirable color rendering index of incandescent lighting. The resulting efficiency is higher than many existing lighting types. The MPC filter is implemented with only a single layer of square lattice or two layers of woodpile-like lattice has high reflection from the photonic band edge to infinitely long wavelength. The MPC filter can be used in a spherical, cylindrical or flat form depending on the illumination scheme.

摘要： Metallic thermal emitters consisting of two layers of differently structured nickel gratings on a homogeneous nickel layer are fabricated by soft lithography and studied for polarized thermal radiation. A thermal emitter in combination with a sub-wavelength grating shows a high extinction ratio, with a maximum value close to 5, in a wide mid-infrared range from 3.2 to 7.8 μm, as well as high emissivity up to 0.65 at a wavelength of 3.7 μm. All measurements show good agreement with theoretical predictions. Numerical simulations reveal that a high electric field exists within the localized air space surrounded by the gratings and the intensified electric-field is only observed for the polarizations perpendicular to the top sub-wavelength grating. This result suggests how the emissivity of a metal can be selectively enhanced at a certain range of wavelengths for a given polarization.

摘要： Nanoscale high-aspect-ratio metallic structures and methods are presented. Such structures may form transparent electrode to enhance the performance of solar cells and light-emitting diodes. These structures can be used as infrared control filters because they reflect high amounts of infrared radiation. A grating structure of polymeric bars affixed to a transparent substrate is used. The sides of the bars are coated with metal forming nanowires. Electrodes may be configured to couple to a subset of the rails forming interdigitated electrodes. Encapsulation is used to improve transparency and transparency at high angles. The structure may be inverted to facilitate fabrication of a solar cell or other device on the back-side of the structure. Multiple layered electrodes having an active layer sandwiched between two conductive layers may be used. Layered electro-active layers may be used to form a smart window where the structure is encapsulated between glass to modify the incoming light.

摘要： Provided are microlens arrays for use on the substrate of OLEDs to extract more light that is trapped in waveguided modes inside the devices and methods of manufacturing same. Light extraction with microlens arrays is not limited to the light emitting area, but is also efficient in extracting light from the whole microlens patterned area where waveguiding occurs.

Such a microlens array is not limited to (O)LEDs of specific emission, configuration, pixel size, or pixel shape. It is suitable for all colors, including white, for microcavity OLEDs, and OLEDs fabricated directly on the (modified) microlens array.
