摘要： A glass is irradiated with a focused pulsed laser beam having a peak power density of 10.sup.5 W/cm.sup.2 or more and a repetition rate of 10 KHz or more. The glass irradiated with the laser beam changes its refractive index at the focal point. During the laser beam irradiation, the glass is continuously moved with respect to the focal point of the pulsed laser beam or continuously scanned with the focused laser beam, so as to form the refractive index changed region (i.e. an optical waveguide) with a predetermined pattern. The glass in which the optical waveguide is formed may be any kind of glass having high transparency.

The glass 1 irradiated with the laser beam 2 changes its refractive index at the focal point 4. During the laser beam irradiation, the glass 1 is continuously moved with respect to the focal point of the pulsed laser beam 2 or continuously scanned with the focused laser beam 2, so as to form the refractive index changed region (i.e. an optical waveguide 5) with a predetermined pattern. The glass 1 in which the optical waveguide 5 will be formed may be any kind of glass having high transparency.

摘要： A glass containing one or more of metal microparticles, semiconductor microparticles, transition metal ion, rare earth ion and anion with characteristic absorption in a wavelength region longer than 360 nm is irradiated with a pulsed laser beam condensed at a focal point preset in an inner part of the glass. The condensed irradiation induces change of a refractive index as well as decrease of characteristic absorption in the wavelength region longer than 360 nm at the focal point. Such the domain is continuously formed by relatively shifting the focal point with respect to the glass. The continuous domains serve as optical waveguides, since optical properties are greatly different between the irradiated part and the non-irradiated part.

摘要： When separated phases are formed in a glass by a nucleation and growth mechanism, a phase separation region only in a small desired area is difficult to form by a conventional method, in which the entire glass is heated. Thus, an optical waveguide structure, or a photonic crystal, which requires an orderly arrangement of high-refractive-index regions, cannot be manufactured. The present invention provides a method for forming a phase separation region by converging a laser pulse in a glass containing a metastable immiscible phase to separate only an area at a focal point of the laser or in the vicinity of the focal point into phases. The focal point of the laser is moved continuously or intermittently relative to the glass to form a linear phase separation region or a dotted phase separation region in two or three dimensions in the glass. The pulse width of the laser is preferably between 10 femtoseconds and 10 picoseconds.
摘要翻译：当通过成核和生长机理在玻璃中形成分离相时，仅通过加热整个玻璃的常规方法难以形成仅在小的期望区域中的相分离区域。因此，不能制造需要高折射率区域有序排列的光波导结构或光子晶体。本发明提供一种用于通过在包含亚稳态不混溶相的玻璃中会聚激光脉冲来形成相分离区域的方法，以仅将激光焦点或焦点附近的区域分离成相。激光的焦点相对于玻璃连续地或间歇地移动，以在玻璃中形成两维或三维的线性相分离区域或点状相分离区域。激光的脉冲宽度优选在10飞秒和10皮秒之间。

摘要： An inorganic body containing rare earth and/or transition metal ions that has been irradiated with a pulsed laser beam in the manner such that a focal point of the pulsed laser beam is adjusted to an inner part of the inorganic body is disclosed. The inorganic body may be a glass or crystal containing one or more of oxide, halide and chalcogenide. The rare earth ion may be one or more of Ce, Nd, Pr, Sm, Eu, Tb, Dy, Tm, Tb. The transition metal ion may be one or more of Ti, Mn, Cr, V, Fe, Cu, Mo and Ru. When the focal point is relatively shifted with respect to the inorganic body, an ionic valence-changed domain is formed with a predetermined pattern at the inner part of the inorganic body. The pulsed laser beam preferably has a pulse width under a picosecond. The ionic valence change occurs at the focal point and its vicinity, but the rare earth or transition metal ion keeps its original valence at all other parts, so as to form a reformed domain with a predetermined pattern in the inorganic body. Since optical properties are selectively changed at the reformed domain, the processed inorganic body is useful as a functional device such as a memory device or a light-emitting device using the differentiated optical properties.

摘要： A wire-grid metal sheet includes a grid portion defined by a plurality of spaced strip-shaped longitudinal members extending longitudinally and cross members extending substantially perpendicular to the longitudinal members. A wire grid is made by attaching the wire-grid metal sheet to a frame. The cross members are arranged at intervals at least about five times greater than those of the longitudinal members. The longitudinal members and the cross members may define a lattice pattern. Alternatively, the longitudinal members or the cross members may be arranged in a staggered manner.
