Optical Waveguides > Planar Optical Waveguide > Thin Film Optical Waveguide Thin Film Optical WaveguideThin Film Optical Waveguide patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/08/07 - 20070258689 - Coupling electromagnetic wave through microcircuit A device includes a waveguide layer formed on a substrate. An ultra-small resonant structure emits electromagnetic radiation (EMR) in the waveguide layer. One or more circuits are formed on the waveguide layer and each operatively connected thereto to receive the EMR emitted by the ultra-small resonant structure. The waveguide layer ... 07/26/07 - 20070172188 - Two-dimensional photonic crystal The present invention provides a two-dimensional photonic crystal in which an absolute photonic band gap (PBG), i.e. a photonic band gap that is effective for both the TE-polarized light and the TM-polarized light within a predetermined wavelength range, is created with an adequate bandwidth. The body 21 is provided with ... 07/26/07 - 20070172187 - Optical sheet body and its producing method, optical card and composite memory An optical card (1) comprising a surface protection sheet (4) laid on the surface (2a) of a core sheet (2) through a surface side adhesive layer (3) functioning as a surface-side clad layer, and a back surface protection sheet (6) laid on the back surface (2b) through a back surface ... 05/24/07 - 20070116420 - Surface plasmon devices A device including an input port configured to receive an input signal is described. The device also includes an output port and a structure, which structure includes a tunneling junction connected with the input port and the output port. The tunneling junction is configured in a way (i) which provides ... 08/03/06 - 20060171649 - Wavelength monitoring and stabilization in wavelength division multiplexed systems Systems and methods for monitoring wavelength in wavelength division multiplexed systems. A thin film filter is used with a pair of photodiodes to monitor the emitted wavelength of a laser. The thin film filter is configured to both reflect and transmit light equally at a particular wavelength of interest. The ... 06/08/06 - 20060120681 - Process for producing filmy optical waveguide The present invention provides a process for producing a filmy optical waveguide from a filmy structure having one or more optical-waveguide parts formed therein, which process comprises: cutting each optical-waveguide part out of the filmy structure to thereby form an optical waveguide having a light entrance end face and a ... 10/13/05 - 20050226584 - Measurement of large strains in ropes using plastic optical fibers A method for the direct measurement of large strains in ropes in situ using a plastic optical fiber, for example, perfluorocarbon or polymethyl methacrylate and Optical Time-Domain Reflectometer or other light time-of-flight measurement instrumentation. Protective sheaths and guides are incorporated to protect the plastic optical fiber. In one embodiment, a ... ### FreshPatents.com Support - Terms & Conditions |
