Abstract: Transmission and reflection type holograms may be formed utilizing a novel polymer-dispersed liquid crystal (PDLC) material and its unique switching characteristics to form optical elements. Applications for these switchable holograms include communications switches and switchable transmission, and reflection red, green, and blue lenses. The PDLC material of the present invention offers all of the features of holographic photopolymers with the added advantage that the hologram can be switched on and off with the application of an electric field. The material is a mixture of a polymerizable monomer and liquid crystal, along with other ingredients, including a photoinitiator dye. Upon irradiation, the liquid crystal separates as a distinct phase of nanometer-size droplets aligned in periodic channels forming the hologram. The material is called a holographic polymer-dispersed liquid crystal (H-PDLC).

Abstract: A method of attaching electrodes to optical substrates with embedded waveguides includes applying the electrode pattern to a separate superstrate from the electro-optic material containing the waveguide. This allows for the change of the index of refraction and/or the dipole moment of an electro-optic material using low voltages. In0 addition, the electrode superstrate can be detached from the waveguide substrate and repositioned and aligned to different waveguides. Removable electrodes add flexibility and increase yield by allowing the electrodes to be re-aligned to the waveguides when improper alignment occurs.

Abstract: The present invention discloses a widely wavelength tunable polychrome colloidal photonic crystal device whose optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimension, effected by a predetermined change in the electronic configuration of the composite material. In its preferred embodiment, the material is a composite in the form of a film or a patterned film or shape of any dimension or array of shapes of any dimension comprised of an organized array of microspheres in a matrix of a cross-linked metallopolymer network with a continuously variable redox state of charge and fluid content. The chemo-mechanical and electro-mechanical optical response of the colloidal photonic crystal-metallopolymer gel is exceptionally fast and reversible, attaining its fully swollen state from the dry shrunken state and vice versa on a sub-second time-scale. These composite materials can be inverted by removal of the constituent microspheres from the aforementioned colloidal photonic crystal metallopolymer-gel network to create a macroporous metallopolymer-gel network inverse colloidal photonic crystal film or patterned film or shape of any dimension optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be redox tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimensions.

Abstract: A photonic switch according to the present invention may be formed using one of a selected group of non-linear optical materials. Each of the materials within this group has a refractive index that demonstrates a substantial peak as a function of wavelength, where the peak occurs at a wavelength distinct from the wavelength of the input signal. A method of producing a photonic switch according to the present invention includes fabricating source and drain waveguides using micro-molding or micro-contact printing processes, or MIMIC (micro-molding in capillaries) of a UV-curable polymer. If desired, a gate waveguide may also be formed in part by these processes. The photonic switch also includes a photonic crystal formed from non-linear optical material, which may be formed, for example, using a block copolymer and nanoparticle composite in a MIMIC or nullfluidics process. Such a process may employ a functionalized mold material to align the blocks.

Abstract: An optical wavelength converting device is provided with a LiTaO.sub.3 substrate, a plurality of inverted-polarization layers periodically arranged in an upper surface of the LiTaO.sub.3 substrate, and an optical waveguide crossing the inverted-polarization layers. The upper surface of the LiTaO.sub.3 substrate is directed toward a -X-crystal axis direction. The inverted-polarization layers are formed by exchanging Ta.sup.+ ions of the LiTaO.sub.3 substrate for H.sup.+ ions, and an extending direction of each inverted-polarization layer is inclined at an angle of .theta. degrees (6.ltoreq..theta..ltoreq.174) to the +C-crystal axis direction toward a -Y-crystal axis direction. The optical waveguide is formed by exchanging Ta.sup.+ ions of the LiTaO.sub.3 substrate and the inverted-polarization layers for H.sup.+ ions to set a refractive index of the optical waveguide higher than that of the LiTaO.sub.3 substrate. The optical waveguide extends in a +Y-crystal axis direction. Fundamental waves polarized in a transverse electric mode induce electric field directed in .+-.Y-crystal axis directions and are converted into second harmonic waves in the optical waveguide.
