摘要： The invention is directed to a process of purifying metal fluoride materials used to make metal fluoride single crystals suitable for making optical elements used in the transmission of wavelengths below 200 nm, and in particular to a process of purifying such materials by the use of a halogen containing plasma to convert metal oxygenates contaminating the feedstocks used in the preparation of the crystals to metal fluorides. The invention also is directed to a process of growing a metal fluoride single crystal using a crystal growth furnace to carry out the foregoing purification procedure followed by the steps of melting the purified material and cooling it using s selected time and temperature cycle to from a metal fluoride single crystal. The plasmas used in practicing the invention can be derived from a variety of halogenated materials including, for example, fluorocarbons, chlorocarbons, boron trihalides, chlorine, fluorine, xenon difluoride and other gaseous or easily volatilized halogenated substances known in the art.

摘要： Methods of fabricating dimensional silica-based substrates or structures comprising a porous silicon layers are contemplated. According to one embodiment, oxygen is extracted from the atomic elemental composition of a silica glass substrate by reacting a metallic gas with the substrate in a heated inert atmosphere to form a metal-oxygen complex along a surface of the substrate. The metal-oxygen complex is removed from the surface of the silica glass substrate to yield a crystalline porous silicon surface portion and one or more additional layers are formed over the crystalline porous silicon surface portion of the silica glass substrate to yield a dimensional silica-based substrate or structure comprising the porous silicon layer. Embodiments are also contemplated where the substrate is glass-based, but is not necessarily a silica-based glass substrate. Additional embodiments are disclosed and claimed.

摘要： A relatively facile, inexpensive method for patterning a layer of glass or a substrate involves patterning a seed material containing a nucleating agent adjacent a layer of thermally crystallizable glass and heat treating the seed material and the layer of thermally crystallizable glass to induce highly oriented crystal growth from the seed material through the thickness of the thermally crystallizable glass layer at selected portions thereof. After the heat treatment, the layer of thermally crystallizable glass is converted into a desired pattern of glass surrounded by crystalline material. The crystalline material is removed with an etchant to leave a desired glass pattern.

摘要： Germanium-silicon oxide, germanium-silicon oxynitride and silica-germania-titania materials and oxynitride materials suitable for fabricating optical waveguides for liquid crystal based cross-connect optical switching devices have a refractive index of from about 1.48 to about 1.52 at 1550 nm, and a coefficient of thermal expansion at room temperature of from about 3×10−6° C.−1 to about 4.4×10−6° C.−1. The compositions are adjusted so that the refractive index of the germanium-silicon oxide, germanium-silicon oxynitride or silica-germania-titania material is closely matched to the refractive index of a typical liquid crystal material whereby improved optical performance of a liquid crystal based cross-connect optical switching device is achieved. The coefficient of thermal expansion of the germanium-silicon oxide, germanium-silicon oxynitride, or silica-germania-titania material is closely matched to the coefficient of thermal expansion of silicon, whereby strain induced birefringence caused by thermal stresses is reduced or avoided.
