摘要： A plasmonic optical device is provided operating in near ultra violet (UV) and visible wavelengths of light. The optical device is made from a substrate and nanoparticles. The nanoparticles have a core with a negative real value relative permittivity of absolute value greater than 10 in a first range of wavelengths including near UV and visible wavelengths of light, and a shell with an imaginary relative permittivity of less than 5 in the first range of wavelengths. A dielectric overlies the substrate, and is embedded with the nanoparticles. If the substrate is reflective, a reflective optical filter is formed. If the substrate is transparent, the filter is transmissive. In one aspect, the dielectric is a tunable medium (e.g., liquid crystal) having an index of refraction responsive to an electric field. The tunable medium is interposed between a first electrode and a second electrode.

摘要： A plasmonic polarizer and a method for fabricating the plasmonic polarizer are provided. The method deposits alternating layers of non-metallic film and metal, forming a stack. A hard mask is formed overlying the stack. The hard mask comprises structures having dimensions and periods between adjacent structures less than a first length, where the first length is equal to (a first wavelength of light/2). The stack is etched through openings in the hard mask to form pillar stacks of alternating non-metallic and metal layers having the dimensions of the hard mask structures. Then, the hard mask structures are removed. In one aspect, subsequent to removing the hard mask structures, the spaces between the pillar stacks are filled with a dielectric material.

摘要： An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.

摘要： An object is to provide a resonator and a vibrator with a high Q value in which dissipation of vibration energy in vibration of the vibrator is small, and a thickness of a support part of the vibrator of a beam structure is made thicker than a thickness of the vibrator and the support part is formed in axisymmetry with respect to a length direction of a beam. By this configuration, brittleness of the support part is improved and loss of vibration energy from the support part is reduced and also loss of vibration energy resulting from surface roughness of a surface of the vibrator can be reduced, so that a resonator having a high Q value can be provided.

摘要： A method is provided for improving metallic nanostructure stability. The method provides a substrate, and using a physical vapor deposition (PVD) process for example, deposits metallic nanostructures having a first diameter overlying the substrate. Some examples of metallic nanostructures include Ag, Au, and Al. The metallic nanostructures are annealed in an atmosphere including an inert gas and H2. The annealing temperature is less than the melting temperature the metal material in bulk form. In response to the annealing, stabilized metallic nanostructures are formed. If the stabilized metallic nanostructures are exposed to an ambient air environment the stabilized metallic nanostructure maintain the first diameter. Typically, the metallic nanostructures are initially formed having a rectangular shape with corners. After annealing, the stabilized metallic nanostructures have a dome shape.
