Abstract: Methods for machining glass structures may be performed on fusion-drawn glass laminates having a core layer interposed between a first cladding layer and a second cladding layer. The core layer may be formed from a core glass composition having a core photosensitivity, the first cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity, and the second cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity. At least one of the core layer, the first cladding layer, and the second cladding layer is a photomachinable layer. The methods may include exposing a selected region of a photomachinable layer in the fusion-drawn laminate to ultraviolet radiation; heating the glass structure until the selected region crystallizes; and removing the crystallized material selectively from the photomachinable layer.

Abstract: A glass sealing sheet comprising a glass core layer having a first side and a second side, a first cladding layer bonded to the first side of the glass core layer, and/or a second cladding layer bonded to the second side of the glass core layer. The first cladding layer is comprises a glass composition that is absorbing of radiation over at least a portion of an emission wavelength range.

Abstract: A free-standing multi-laminate hermetic sheet includes a first carrier film, a hermetic inorganic thin film formed over the first carrier film, and a second carrier film formed over the hermetic inorganic thin film. A workpiece can be hermetically sealed using the multi-laminate sheet, which can be applied to the workpiece in a step separate from a formation step of either the multi-laminate sheet or the workpiece.

Abstract: The invention is directed to glass articles having improved resistance to edge fracture resulting from armoring the edges using metallic material adhesively bonded to the edges of the glass article. In one embodiment the metallic edge material is machinable to enable final finish of the part to specification tolerances. One of a plurality of layers of the metallic material can be applied to edge.

Abstract: A fluid encapsulated MEMS optical switch includes an optical waveguide matrix with MEMS mirrors situated in trenches located at waveguide cross-points. The trenches are filled with collimation-maintaining fluid and the mirrors are immersed therein. The collimation maintaining fluid prevents the light beam from spreading when it enters the switch cross-points. This feature enables the use of much smaller MEMS mirrors and prevents some of the typical MEMS mirror problems found in the related art. In particular, the MEMS mirror disclosed in the present invention is reduced to approximately 15 &mgr;m wide and 2 &mgr;m thick, resulting in shorter actuation distances of approximately 15 &mgr;m. This feature results in an optical switch having faster switching times.
