Abstract: A method of producing a radiation-induced colorant transfer image on a support, includes the steps of: providing an image-receiving element comprising a support having thereon an image-receiving layer; providing a colorant donor element having a colorant transfer layer on a colorant element support and wherein colorant can be transferred from a transfer surface of the colorant donor element to the image-receiving layer in response to selectively applied radiation; providing a rigid element being configured to provide a surface having peaks and valleys; pressing either the colorant element support surface or the image-receiving support surface against the rigid element so as to cause either the colorant transfer layer surface or the image-receiving surface, respectively, to conformally have peaks and valleys; causing the peaks of the colorant transfer layer or the image-receiving layer to engage either the image-receiving element or the colorant donor element, respectively; and applying radiation to the colora

Abstract: A method of producing a color filter array on a transparent support, includes the steps of: forming a polymer image-receiving layer on the transparent support; baking the polymer image-receiving layer on the transparent support so as to harden the polymer image-receiving layer; and imagewise thermally transferring different colorants to form multicolored pixels in the polymer image-receiving layer. The method further includes fixing the colorant pixels into the polymer receiving layer to form the color filter array; and coating the such formed color filter array with an overcoat.

Abstract: A fully integrated electro-optic page-scanner comprises an optically-transparent waveguide made from an electro-optic polymer formed as a Langmuir-Blodgett film, and a linear array of electrically-addressable, spaced, parallel electrodes for selectively altering the refractive index across pixel-sized portions of the polymeric waveguide. Parallel addressing of the electrodes in accordance with the intensity pattern of a line of pixels to be recorded acts to modulate the phase front of an optical wave propagating within the waveguide in accordance with such line intensity pattern. Schlieren optics, also integrated with the page-scanner, convert the phase-front-modulated wave to an intensity-modulated pixel pattern which can be imaged onto a moving photosensitive recording element to record a two-dimensional (page) of image information. By using an electro-optic polymer formed as a Langmuir-Blodgett film as the waveguide, certain disadvantages of prior art scanning devices are eliminated.

Abstract: An electro-optic waveguide deflector appropriate for use in an optical pickup head uses any film exhibiting high second order susceptibility such as nonlinear optic organic Langmuir-Blodgett films or nonlinear optic organic poled polymer films, or a liquid-crystal overlay cell. The deflector comprises a base support, a planar electrode layer disposed on the base support, a first buffer layer atop the first electrode layer, and an optical waveguide layer overlying the first buffer layer and planar electrode. When nonlinear optic films are used to form the waveguide layer, a second buffer layer is disposed atop the waveguide layer, and a pair of spaced electrodes is disposed atop the second buffer layer. When a nematic-type liquid-crystal overlay cell is used, it is disposed atop a passive dielectric waveguide, and a pair of spaced electrodes is disposed on the under surface of the liquid-crystal cell cover plate.

Abstract: An integrated optical head has first and second channels forming an interferometer. A electro-optically phase-shiftable waveguide channel is associated with one of the first and second channels of the interferometer for electro-optical phase shifting of one channel with respect to the other channel. The interferometer is formed on a silicon substrate and the phase-shiftable waveguide channel is formed of Langmuir-Blodgett thin-film electro-optic polymers described on the silicon substrate.
