Abstract: A method for forming a substantially flat planar lightwave optical circuit which has a substantially flat planar silica substrate and a sintered glassy lightguiding layer over the silica substrate. The structure is given a post treatment at an elevated temperature for a time sufficient to flatten said structure and compensate for distortion. Alternatively, the silica substrate may be heated and presagged to a predetermined degree to compensate for distortion or warpage which will occur in later processing.

Abstract: A method of molding precision glass optical elements or lenses is disclosed. Precision molded glass molds are first provided which define a glass mold cavity having a predetermined desired size, shape and volume corresponding to the glass optical element. To facilitate formation of the glass optical elements, shaped and polished preforms are formed. An apparatus for molding glass optical elements by means of at least one molded glass mold is disclosed. The optical element, which may be a lens and which may be formed of glass, is molded within an apparatus that comprises a pair of molds of which at least one is a molded glass mold, a contraining means and a ring disposed intermediate the molds. The interior diameter of the ring and the mold surfaces of the molds comprise the optical element molding cavity.

Abstract: A strengthened glass sheet product as well as a process and an apparatus for making the product. The process comprises cooling the glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened glass sheets having improved breakage properties.

Abstract: A method and apparatus for drawing glass objects from glass feedstock, wherein a dimension of the glass object is measured on-line and controlled by a control structure which compensates for the deadtime between a change to the drawing speed and the measurement of the effect of that change to the measured dimension. The model which compensates for the deadtime is preferably nonlinear, and the control gains and model parameters are preferably continuously calculated during the drawing process. The invention is particularly applicable to drawing optical waveguide cane from optical waveguide preforms.

Abstract: A strengthened architectural glass or glass-ceramic sheet or article as well as processes and systems for making the strengthened architectural glass or glass-ceramic sheet or article is provided. The process comprises cooling the architectural glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened architectural glass sheets that may be incorporated into one or more panes in single or multi-pane windows.

Abstract: A flat planar light wave optical circuit is formed by a method(A) comprising: (i) forming a layer of a plurality of oxide compounds on the surface of a flat planar silica substrate, (ii) sintering the oxide layer to form a glassy light guide layer, (iii) heating the structure at an elevated temperature for a time sufficient to flatten the structure, (iv) forming an optical circuit into the glassy layer by photolithography and etching, and (v) cladding the surface with a glassy layer having the same index of refraction as the substrate.
