| 20080245108 | METHOD OF MANUFACTURING OPTICAL WAVEGUIDE USING OPTICAL SOLITON - There is provided a method of manufacturing an optical waveguide, the method including: allowing a beam to be incident in an optical waveguide direction of an optical waveguide material; generating an optical solution in the optical waveguide material by adjusting intensity of the incident beam according to the optical waveguide material; allowing the incident beam to be re-incident at an intensity higher than an intensity of the incident beam after checking generation of the optical solution in the optical waveguide material; and increasing a refractive index of an optical solution-generating area of the optical waveguide material by the re-incident beam to thereby form an optical waveguide. | 10-09-2008 |
| 20080282741 | PRODUCTION METHOD OF OPTICAL WAVEGUIDE - A production method of an optical waveguide includes: preparing a laminated body that includes a first clad layer and, on the first clad layer, a core layer and a second clad layer alternately laminated in this order so that two or more of the core layer are included in the laminated body; forming a light-propagating waveguide core by cutting the laminated body so as to reach but not cut through the first clad layer from a side where the core layer and the second clad layer are laminated; and embedding at least a cut portion of the laminated body with a third clad layer. | 11-20-2008 |
| 20080289366 | PRODUCTION METHOD OF OPTICAL WAVEGUIDE - A production method of an optical waveguide includes: preparing a laminated body that includes a first clad layer and at least a core layer laminated on the first clad layer; forming a light propagating optical waveguide core by cutting the core layer by use of a dicing saw from a side where the core layer is laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer; and embedding at least a cut portion of the laminated body with a second clad layer. | 11-27-2008 |
| 20090133444 | Method of manufacturing optical board - A method of manufacturing an optical board is disclosed. The method of manufacturing an optical board may include stacking an optical waveguide core layer over a first optical waveguide cladding layer, forming an inclined surface by diffracting a laser with a mask to remove a portion of the optical waveguide core layer, and stacking a reflective layer over the inclined surface. | 05-28-2009 |
| 20110138860 | SILICA-ON-SILICON WAVEGUIDES AND RELATED FABRICATION METHODS - True time delay silica waveguides and related fabrication methods are disclosed. Also disclosed are true time delay silica waveguides comprising wedged silica structures. | 06-16-2011 |
| 20130074551 | METHOD OF MAKING MULTI-CORE OPTICAL FIBER AND METHOD OF MAKING MULTI-CORE OPTICAL FIBER CONNECTOR - The present invention, even in the case where the size of a preform itself is increased, enables production of a multi-core optical fiber in which cores are arranged with high accuracy. A plurality of core members each being rod-like are fixed by an array fixing member while a relative positional relation of the plurality of core members is fixed, and the plurality of core members and a cladding member are integrated into one piece, and thus a preform is obtained. By drawing the obtained preform, a multi-core optical fiber in which core arrangement is controlled with high accuracy is obtained. | 03-28-2013 |
| 20130167594 | POLARIZATION CONTROLLING OPTICAL FIBER PREFORM AND PREFORM FABRICATION METHODS - Methods to fabricate an optical preform for draw into Polarization Maintaining (PM) or Polarizing (PZ) optical fiber are provided. The methods involve assembly of pre-shaped and pieced together bulk glass elements into preforms (“assembled preforms”) for simultaneous fusing and drawing into optical fiber. These preforms form a stress-induced birefringent optical core when drawn to fiber. | 07-04-2013 |
