摘要： A reflective polarzier for visible light wavelengths formed of a plurality of polarizer units. Each polarizer unit having a transparent, inorganic substrate with first and second opposing surfaces. The first surface is coated with a single layer of a dielectric material, and the second surface is coated with a layer of a highly reflective metal film or a dielectric material. The polarizer is configured to produce a “quasi-straight path,” such that a light ray exiting the substrate is substantially parallel with a corresponding, incident light ray entering the substrate. The polarizer exhibits polarization over the entire visible spectrum.

摘要： A method of writing a pattern, such as a waveguide, in a bulk glass substrate. The bulk glass substrate can be formed from, for example, borosilicate or sulfide or lead glass. A pulsed laser beam is focused within the substrate while the focus is translated relative to the substrate along a scan path at a scan speed effective to induce an increase in the refractive index of the material along the scan path. Substantially no laser induced physical damage of the material is incurred along the scan path. Various optical devices can be made using this method.

摘要： Method of patterning or forming color gradients and/or designs on a glass surface are disclosed. Patterns are formed by depositing a film of metal on at least one surface of the glass; forming a layer of photoresist over the metal; exposing the article to light through a mask which contains a desired pattern; developing the piece to remove the exposed photoresist to reveal the underlying metal; removing the underlying metal to reveal the underlying glass; and removing the unexposed photoresist to reveal the underlying metal. To form color gradients or color patterns, the glass article is further treated in hydrogen at a temperature in the range of 300-600.degree. C. to effect the desired surface coloration.

The structure comprises a non-waveguiding body of optical material having a concentration of a photorefractive-sensitive component in the body such that upon irradiation of a part of the body by a beam of actinic radiation, the refractive index of the irradiated part is increased. The method of making the optical component comprises providing a non-waveguiding body of optical material; providing a concentration of a photorefractive-sensitive component in the body; contacting the non-waveguiding body of optical material with an atmosphere comprising one of hydrogen, deuterium and mixtures thereof; and exposing a part of the non-waveguiding body of optical material to actinic radiation such that the refractive index of the exposed part is increased.

摘要： An ophthalmic lens of photochromic glass having an R.sub.2 O-Al.sub.2 O.sub.3 -B.sub.2 O.sub.3 -SiO.sub.2 base glass composition and a method of producing the lens. The lens contains precipitated cuprous halide crystals that are elongated and oriented, whereby the lens is capable of polarizing light when the lens is in the darkened state. If at least a portion of the crystals in at least a surface layer on the lens are reduced to copper metal, the lens exhibits a permanent dichroic behavior. The lens provides effective polarization of radiation across the entire visible wavelength region of the spectrum, has a sharp spectral cutoff for radiation below the 400 nm wavelength, thereby eliminating UV transmission, and has a transmittance not over about 40% in the darkened state.
