    摘要: Recent theoretical investigations have predicted the existence of axially frozen modes that arise when light is incident upon an anisotropic two-dimensional photonic crystal. Such electromagnetic modes are of interest since they suggest a near-zero group velocity with extraordinary amplitudes. The present invention addresses the crystal physics associated with realizing such effects and provides for the development of materials suitable for use in the forming photonic crystals that can exhibit such effects.

    摘要: Optical waveguides interconnect optical information processing devices, or connect such devices with other optical communication links such as glass optical fibers. Fluoropolymers consisting of alternating perfluorocyclobutane and aryl ether linkages possess suitable properties for optical waveguides and other devices due to tunability in optical properties of the copolymers. Perfluorocyclobutane (PFCB) copolymer may be employed in solutions that exhibit a high solids content. Such solutions show useful physical properties for optical waveguide devices since the solutions are capable of achieving single step film thicknesses, when applied to a substrate, of greater than about 0.6 microns, and sometimes may achieve a thickness of 10 microns or more.

    摘要: Disclosed are layered nanoparticles including multiple dopants constrained in discrete layers of the particles. Through predetermination of the architecture of the nanoparticles, energy transfer between the active ions can be controlled. Active ions can be provided in discrete sections of the nanoparticles so as to allow complete, partial, or no energy transfer between the optically active ions. In one embodiment, the emission spectra of a single nanoparticle can be equivalent to the spectrum of a blend of singularly doped nanoparticles, providing for composite materials with improved homogeneousness and multiple emissions from a single excitation wavelength. The layered nanoparticles can be, for example, core/shell nanoparticles.
