The invention relates to a polycrystalline IR transparent material produced by sintering chalcogenide powder, e.g., ZnS powder, using hot uniaxial pressing followed by hot isostatic pressing. The microstructure of the material described in this disclosure is much finer than that found in material produced using the state of the art process. By using a powder with a particle size fine enough to improve sintering behavior but coarse enough to prevent a lowering of the wurtzite-sphalerite transition temperature, a highly transparent material with improved strength is created without degrading the optical properties. A high degree of transparency is achieved during hot pressing by applying pressure after the part has reached a desired temperature. This allows some degree of plastic deformation and prevents rapid grain growth which can entrap porosity. The crystallographic twins created during this process further inhibit grain growth during hot isostatic pressing.

A multilayer armor is provided that includes a first rigid layer, a second rigid layer, and an interlayer securing the first and second rigid layers to one another. At least one of the first and second rigid layers can include a plurality of regions with a physical or material property that varies between the regions. The interlayer can have a force-extension ratio of 5,600 psi/in or less. The interlayer can have a physical or material property that varies within the interlayer.

The invention relates to an optical scattering element suitable for dispersing or scattering light transmitted by optical device by Mie scattering. The optical scattering element comprises a phase-separated or porous borosilicate glass having dispersed phase particles with a particle size of 200 to 500 nanometers or pores with a size of 200 to 500 nanometers, at a number density of 10to 10mm. The optical scattering element can be prepared by subjecting a borosilicate glass to a controlled heat treatment to induce phase separation, and then optionally leaching out one of the phases with an acid leach. The optical scattering element can be, for example, attached to an end of an optical fiber or bundle of optical fibers. The invention also relates to a method of dispersing or scattering light by transmitting the light through the optical scattering element.

The invention relates to an optical fiber comprising a core and a cladding, wherein the core is made of a glass composition having a near-zero electrostrictive coefficient M, to reduce the effect of stimulated Brillouin Scattering (SBS). The invention further relates to a compensation fiber segment for connection to a silica optical fiber, the compensation fiber segment being made of a glass composition having an electrostrictive coefficient that opposes that of the silica optical fiber so that an acoustic wave transmitted to compensation fiber segment from the silica optical fiber will generate an acoustic wave within the compensation fiber segment that is about 180 degrees out of phase with the that acoustic wave transmitted from the silica optical fiber, thereby minimizing the effect of stimulated Brillouin Scattering.

A method of forming a through-glass via hole involves providing a glass substrate having first and second substantially planar parallel surfaces; masking the first and second substantially planar parallel surfaces to form a via-patterned portion thereon; and etching the via-patterned portion on the first and second substantially planar parallel surfaces to form a first channel in the first substantially planar parallel surface and a second channel in the second substantially planar parallel surface. The first channel and second channel are substantially orthogonal or non-orthogonal to one another. The first channel and the second channel intersect to form a quadrilateral through-glass via hole having via openings at the first and second substantially planar parallel surfaces. A low cost, low complexity and high reliability method for producing a glass substrate having a plurality of through-glass via holes such that the glass substrate can be used, for example, as an interposer.

A transparent laminate structure is provided that includes two transparent layers, a transparent interlayer, and an inorganic barrier layer. The two transparent layers each have an inner face and a side edge. The transparent interlayer is between and laminates the inner faces of the two transparent layers to one another. The transparent interlayer also extends over the side edges of the two transparent layers and laminates the inorganic barrier layer to at least the side edges of the two transparent layers.

The present invention relates to a method of bonding a gold surface to a second surface which comprises heating a hybrid organic-inorganic melting gel &#x3e;50&#xb0; C., applying the melting gel to either the gold surface or the second surface. The melting gel is heated to above 130&#xb0; C. until the melting gel has cured sufficiently to bond the surfaces together. The invention also relates to a combination of a gold surface and a second surface that is bonded together with a hybrid organic-inorganic melting gel. In another aspect of the invention the hybrid organic-inorganic melting gel is heated to a workable viscosity and cast into a film, sheet, block or lens. The cast gel is cured or partially cured and then applied between the gold surface and the second surface. Additional uncured melting gel may be applied. The construct is heated to above 130&#xb0; C. until the melting gel has cured sufficient to bond the surfaces together.
