Abstract:
The glass-based THz optical waveguides (10) disclosed herein are used to guide optical signals having a THz frequency in the range from 0.1 THz to (10) THz and include a core (20) surrounded by a cladding (30). The core has a diameter D1 in the range from (30) μm to 10 mm and is made of fused silica glass having a refractive index n1. The cladding is made of either a polymer or a glass or glass soot and has a refractive index n2
Abstract:
A high silica content substrate, such as for a device, is provided. The substrate has a high silica content and is thin. The substrate may include a surface with a topography or profile that facilitates bonding with a conductive metal layer, such as a metal layer for a circuit or antenna. The substrate may be flexible, have high temperature resistance, very low CTE, high strength and/or be non-reactive. The substrate may be suitable for use in circuits intended for use in high temperature environments, low temperature environments, reactive environments, or other harsh environments. The substrate may be suitable for high frequency antenna applications.
Abstract:
The present disclosure is directed to the use of glass wafers as carriers, interposers, or in other selected applications in which electronic circuitry or operative elements, such as transistors, are formed in the creation of electronic devices. The glass wafers generally include a glass having a coefficient of thermal expansion equal to or substantially equal to a coefficient of thermal expansion of semiconductor silicon, an indexing feature, and a coating on at least a portion of one face of the glass.

Abstract:
A method of coating a surface of a glass ribbon during a drawing process using atmospheric vapor deposition is provided. The method includes forming a glass ribbon in a viscoelastic state, desirably with a fusion draw. The glass ribbon is drawn in the viscoelastic state. The glass ribbon is cooled in the viscoelastic state into an elastic state. The glass ribbon is directed into an open end of a reactor. The reactor includes multiple channels. A first channel directs a first reactant gas, a second channel directs a second reactant gas and one or more third channels draw excess reactant, or purge it with inert gas flow, or both.

Abstract:
Methods and apparatus provide for a touch sensitive display, which may include: a display layer; a cover glass layer formed from ion exchanged glass; and an optional touch glass layer, where, either on a first side of the touch glass or on a first side of the cover glass, a grid of electrode traces is disposed, which is sensitive to distortions of a local electrostatic field caused by a touching event, and the grid may be positioned between the display layer and the cover glass layer.
