Abstract: The invention relates to a glass excellent in infrared absorption capability and corrosion resistance, and its fabrication process. A compound of divalent copper and a compound of a metal species for a network modifier oxide are introduced in a wet gel. Then, the wet gel is dipped in a dipping solution having a low solubility with respect to the compound of divalent copper and the compound of a metal species for a network modifier oxide for the precipitation in the wet gel of the divalent-t copper compound and the compound of a metal species for a network modifier oxide, followed by drying and firing. Thus, an infrared absorbing glass comprising 70 to 98 mol % of SiO2, 1 to 12 mol % of CuO and 1 to 18 mol % of a network modifier oxide other than CuO is fabricated.

Abstract: A non-phase separable glass material for fabricating a GRIN lens comprises 5-20 mole % boron oxide and ratio R of network modifiers in mole % to the network former boron oxide in mole % is in the range of about 1-1.5. The melted preform of such glass material is extruded through an opening to form a glass rod where the extrusion process eliminates bubbles that may be present in the preform. Neodymium oxide may be added in the frit material for forming the preform to reduce friction forces in the extrusion process and reduces the stress in the glass rod. Centerless grinding may be performed to control the diameter and roughness of the surface of the rod to control the diffusion parameters during the subsequent ion-exchange.

Abstract: An active single-mode optical fiber has the core made of a rare earth doped non-oxide glass and the cladding made of an oxide glass. The glass of the core has a melting temperature lower than that of the glass of the cladding and lying within the range of the softening temperatures of the latter. In a preferred embodiment the core is made of a chalcogenide glass and the cladding is made of a lead silicate glass. To produce the fiber, a preform, obtained by introducing an element made of the non-oxide glass into the hole of a capillary tube made of the oxide glass, is brought to a temperature lying within the range of softening temperatures of the oxide glass and not lower than the melting temperature of the non-oxide glass, and is drawn. The capillary tube, during the drawing process, serves as a container for the molten glass of the core.

Abstract: Relatively large bodies of low-alkali silicate and other glass can be prepared conveniently by a particulate sol-gel process. The glass comprises at least 85 mole % SiO.sub.2, 1-12 mole % oxide of one or more of Li, Na, K, Rb, Cs, Ti and Zr, 0-6 mole % of oxide of Al, and optionally at most 2.5 mole % of oxide of elements other than Si, Li, Na, K, Rb, Cs, Ti, Zr and Al. The process comprises forming particles from a first sol that comprises Si and one or more of Li, Na, K, Rb, Cs, Ti and Zr, and optionally additionally comprises Al. The process further comprises forming a second sol by dispersing the particles in an aqueous liquid, gelling the second sol, and heat treating the resulting gel body such that the glass results.

Abstract: Disclosed is a method of forming a doped glass article. Heated glass particles are deposited on a mandrel where they adhere together to form a porous glass preform having interconnective pores. The mandrel is removed to form a tubular preform having an axial aperture. The preform is suspended in a consolidation furnace by a gas conducting handle having a dopant containing chamber. As the handle and preform are heated, there is flowed through the chamber a gas that reacts with the heated dopant to form a reactant gas that flows into the aperture and into pores, whereby a dopant is incorporated into the porous glass preform. The doped preform is heat treated to consolidate it into an elongated non-porous glass body containing the dopant. The glass body can be provided with cladding glass and drawn into an optical fiber.

Abstract: In accordance with the present invention, the dopant within one gradient index optical element has two independent concentration distributions. Particularly to use the present invention to obtain a gradient index optical element having an excellent chromatic aberration correction ability, it is only needed to make such dopant distributions as shown in the previously stated Japanese Patent Application No. 280897/1989. However, as to the doping of a dopant into a porous body, there is a limit in the amount which can be doped. This is a disadvantage of the molecular stuffing method, but the reason for this is that the dopant must be supplied into the holes as a solution and it is largely restricted by the solubility of the dopant in the solvent. In addition, since the intra-hole fixing of the dopant depends on the solubility difference by temperature or that by solvent exchange, it is further restricted. For this, the latter process which is an application of the molecular stuffing method preferably takes the distribution that has less doping amount.Accordingly, a large concentration distribution must be provided to the dopant in the preceding process. For that, the preceding process is desirably a gel which has sufficiently large concentration gradient by the sol-gel method. However, the sol-gel method also has a defect, in which the distribution provision relies on the elution of the dopant metal, and thus a convex distribution is easier to produce in principle.In view of the foregoing, it is the most effective that the concentration gradient of the first dopant is formed in a convex shape by the sol-gel method using alcoxide as the raw material for retreiving the first dopant, and that the concentration gradient of the second dopant is formed in a concave shape by an application of the molecular stuffing method.

Abstract translation: 根据本发明，一个梯度折射率光学元件内的掺杂剂具有两个独立的浓度分布。 特别是为了使用本发明获得具有优异的色像差校正能力的梯度折射率光学元件，仅需要进行如前述日本专利申请280897/1989所示的掺杂剂分布。 然而，关于将掺杂剂掺杂到多孔体中，可以掺杂的量存在限制。 这是分子填充方法的缺点，但其原因是必须将掺杂剂作为溶液供给到孔中，并且其很大程度上受掺杂剂在溶剂中的溶解度的限制。 此外，由于掺杂剂的孔内固定取决于温度下的溶解度差异或通过溶剂交换的溶解度差异，因此进一步受限制。 为此，作为分子填充方法的应用的后一种方法优选具有较少掺杂量的分布。 因此，在前述方法中必须向掺杂剂提供大的浓度分布。 为此，上述方法理想地是通过溶胶 - 凝胶法具有足够大的浓度梯度的凝胶。 然而，溶胶 - 凝胶法也存在缺陷，其中分配条件依赖于掺杂剂金属的溶出，因此原理上更容易产生凸分布。 鉴于上述，最有效的是通过溶胶 - 凝胶法将第一掺杂剂的浓度梯度形成为凸形，其中使用的是以氧化铝作为回收第一掺杂剂的原料，并且， 通过使用分子填充方法将第二掺杂剂形成为凹形。
