Abstract: A nanocomposite material that is both transparent and electrically conductive is provided. The nanocomposite comprises a nanoporous matrix, preferably formed from nanoparticles, that is internally coated with a transparent conductive material to define an internal conductive path within the nanocomposite. The nanocomposite is substantially transparent over a defined spectral range that preferably includes at least a portion of the visible spectrum, and preferably comprises pores with a mean diameter of less than approximately 25 nm. A bilayer may be formed by depositing a layer of a transparent conductive material on top of a nanocomposite layer, or by depositing a second layer of a nanocomposite having different optical properties. The nanocomposites formed using a combination of sequential and/or concurrent deposition techniques are correspondingly discrete and/or continuously varying structures.

Abstract: In a 2D photonic crystal waveguide comprising a 2D photonic crystal structure based on a slab (11) formed of a material having a higher refractive index than air, in which a material (16) having a lower refractive index than the slab material is periodically arrayed to provide a refractive index distribution, a photonic crystal waveguide is created by forming a line defect (12), which functions as a waveguide, in the periodic array of photonic crystal, and at least one point defect (14) is disposed adjacent the photonic crystal waveguide to act as a disorder in the periodic array of photonic crystal. The point defect functions as a light or electromagnetic radiation outlet/inlet port for trapping light or electromagnetic radiation of a selected wavelength among light or electromagnetic radiation propagating through the waveguide and radiating it, or trapping light or electromagnetic radiation of a selected wavelength from the exterior and introducing it into the waveguide.
