Abstract: A method of forming a liquid lens, comprising the steps of: positioning a first substrate defining a hole over a second substrate, wherein a cavity is defined within the second substrate and aligned with the hole; dispensing a second liquid into the cavity defined within the second substrate; capping the second liquid with a first liquid dispensed through the hole, wherein the first liquid and the second liquid have different refractive indices than each other; and translating at least one of the first substrate and the second substrate such that the hole is not aligned with the cavity.

Abstract: Layered glass structures and fabrication methods are described. The methods include depositing soot on a dense glass substrate to form a composite structure and sintering the composite structure to form a layered glass structure. The dense glass substrate may be derived from an optical fiber preform that has been modified to include a planar surface. The composite structure may include one or more soot layers. The layered glass structure may be formed by combining multiple composite structures to form a stack, followed by sintering and fusing the stack. The layered glass structure may further be heated to softening and drawn to control linear dimensions. The layered glass structure or drawn layered glass structure may be configured as a planar waveguide.

Abstract: A system and method for sintering a thin, high purity fused silica glass sheet having a thickness of 500 μm or less, includes a step of rastering a beam of a laser across a sheet of high purity fused silica soot; wherein a pattern of the rastering includes tightly spacing target locations on the sheet such that the laser sinters the soot and simultaneously forms tiny notches on a first major surface of the sheet when viewed in cross-section, wherein the tiny notches are crenellated such that at least some of the notches have generally flat bottom surfaces and at least some respective adjoining caps have generally plateau top surfaces offset from the bottom surfaces by steeply-angled sidewalls.

Abstract: A method of making an LED device and an LED device using a high-silica, fully-sintered glass substrate is provided. The high-silica substrate is at least 99% silica and is thin, such as less than 200 μm in thickness. A phosphor containing layer is deposited on to the substrate and is laser sintered on the substrate such that a portion of the sintered phosphor layer embeds in the material of the substrate.

Abstract: A high silica content substrate, such as for a thin-film battery, is provided. The substrate has a high silica content, such as over 90% by weight silica, and is thin, for example less than 500 μm. The substrate may include a surface with a topography or profile that facilitates bonding with a coating layer, such as a coating of an electrochemical battery material. The high silica content substrate may be flexible, have high temperature resistance, high strength and/or be non-reactive. The substrate may be suitable for use in the high temperature environments used in many chemical deposition or formation processes, such as electrochemical battery material formation processes.
