Abstract: The invention concerns a quartz glass body for an optical component for the transmission of UV radiation with a wavelength of 250 nm and less, especially for a wavelength of 157 nm, as well as a process for the manufacture of the quartz glass body where fine quartz glass particles are formed by flame hydrolysis of a silicon compound, deposited and vitrified. Suitability of a quartz glass as represented by high base transmission and radiation resistance depends on structural properties caused by local stoichiometric deviations, and on the chemical composition. The quartz glass body according to the inventions is distinguished by a uniform base transmission (relative change of base transmission ≦1%) in the wavelength range from 155 nm to 250 nm (radiation penetration depth of 10 mm) of at least 80%, a low OH content (less than 10 ppm by weight) and a glass structure substantially free from oxygen defect centers. A quartz glass body of this kind is manufactured by a process which allows bulk embedding of hydrogen or oxygen into the glass network in that at least a two stage heat treatment takes place at temperatures ranging from 850° C. to 1600° C. before the vitrification, the last stage comprising sintering at a temperature between 1300° C. and 1600° C. in an atmosphere containing hydrogen or oxygen, or a nonflammable mixture of these substances.

Abstract: A nonlinear optical silica material mainly consisting of SiO2—GeO2 to which hydrogen or halogen element X is added. Oxygen bonded to Ge contained in the nonlinear optical silica material is replaced by H or X, and one Ge has two Ge—O bonds and one Ge—H (or Ge—X) bond at Ge· points where nonlinearity is exhibited in the silica material. The Ge—H (or Ge—X) bond does not relate to a crystal network, so that when the polarity is oriented in order to exhibit nonlinearity at Ge·, an electric field to be applied can be lowered, and when a optical semiconductor hybrid element or the like is produced, other portions of the semiconductor elements can be prevented from being broken or degraded in performance. An insulating film can be interposed between the semiconductor substrate and the nonlinear optical silica film to prevent undesired impurities from dispersing into the semiconductor substrate and other elements and preventing a defect from being caused in the crystal of the substrate due to the silica film.
