摘要:
A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. In one embodiment, the hermetically sealed glass package is manufactured by providing a first substrate plate and a second substrate plate. The second substrate contains at least one transition or rare earth metal such as iron, copper, vanadium, manganese, cobalt, nickel, chromium, neodymium and/or cerium. A sensitive thin-film device that needs protection is deposited onto the first substrate plate. A laser is then used to heat the doped second substrate plate in a manner that causes a portion of it to swell and form a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the thin film device. The second substrate plate is doped with at least one transition metal such that when the laser interacts with it there is an absorption of light from the laser in the second substrate plate, which leads to the formation of the hermetic seal while avoiding thermal damage to the thin-film device. Another embodiment of the hermetically sealed glass package and a method for manufacturing that hermetically sealed glass package are also described herein.

摘要:
The invention includes methods of stabilizing negative thermal expansion glass-ceramic optical waveguide substrates. The invention includes the stabilized negative thermal expansion glass-ceramic optical waveguide substrates. The stabilized substrates have very stable physical characteristics such as dimensional length when exposed to extreme environments. The stabilized substrates are used to athermalize optical waveguide devices such as optical fiber grating. The stabilized substrates are particularly well suited for providing athermalized fiber Bragg grating.

Glass frit compositions, calculated in mole percent on an oxide basis, consisting essentially of 24.5 to 29.0% P2O5; 1.0 to 5.0% B2O3; 1.0 to 2.0% Al2O3; and sufficient amounts of SnO and ZnO (51.5 to 66.5% SnO, and 5.0-12.0% ZnO), wherein the molar ratio of SnO:ZnO is in the range of about 5.0:1 to 12:1, and 0.0 to 2.0% SiO2. The glass compositions exhibit, under NMR spectroscopic analysis of 11B nuclei, a signal containing at least two peaks at a chemical shift in the range of approximately −18 to −25 ppm. The frit compositions exhibit long term stability, durability, and resistance to attack against moisture in high temperature and humidity conditions and are capable of attaching optical fiber Bragg gratings without the use of a hermetic chamber and the like. An optoelectronic device that employs a sealing material that comprises a frit made from the glass compositions.
