20110280539 | WAVEGUIDE STRUCTURE AND RELATED FABRICATION METHOD - A method for fabricating a waveguide structure (i.e., preferably an optical waveguide structure) uses a two mask process step sequence for forming a waveguide layer over a substrate. A first mask within the two mask step process sequence is used to etch the substrate to provide a pillar within the substrate. A second mask within the two mask process step sequence is self aligned to, and covers a top and at least a portion of the sidewalls of, the pillar. The second mask is used as a thermal oxidation mask that provides an optical waveguide layer from a top portion of the pillar that is separated from a thinned substrate derived from the substrate by a waveguide isolation layer formed from thermal oxidation of at least a bottom portion of the pillar. Under conditions of manufacturing economy, and as a result of the processing sequence, the waveguide layer is formed with a non-planar bottom surface including a valley in the bottom surface of the waveguide layer and the substrate is formed with a non-planar top surface including a peak in the top surface of the substrate that corresponds with the valley in the bottom surface of the waveguide layer. | 11-17-2011 |

20130236153 | METHOD OF MANUFACTURING OPTICAL FIBERS, TAPERED OPTICAL FIBERS AND DEVICES THEREOF - Optical fibers and optical fiber tapers have application within many optical systems and optical devices. To date manufacturing such fibers and fiber tapers has been restricted to drawing constant diameter fibers in gravity driven processes and symmetric tapers through pulling with localized heating. However, it would be beneficial to be able to generate arbitrary profiles when pulling an optical fiber into a fiber taper allowing an initial uniform section, reducing transition, wire section, increasing transition and final uniform section. Further, the technique further allows novel optical fiber geometries to be fabricated, which the inventors refer to a hybrid tapers wherein additional elements such as coatings, which provide mechanical and environment protection, may be incorporated into the initial preform and processed simultaneously with the fabrication of the optical taper such that the final fabricated hybrid tapers are mechanically robust and handlable thereby improving manufacturing yield and reducing cost. | 09-12-2013 |
