A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display is manufactured by providing a first substrate plate and a second substrate plate and depositing a frit onto the second substrate plate. OLEDs are deposited on the first substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the OLEDs. The frit is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source heats the frit, it softens and forms a bond. This enables the frit to melt and form the hermetic seal while avoiding thermal damage to the OLEDs.
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:
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.

A method for splicing optical fibers is disclosed. The fibers are held by ferrules with a softening temperature at least 30° C. below that of the lower of the glass transition temperatures of the fibers. The ends of the fibers are actively aligned and brought into contact, then energy is applied to fuse the ferrules together, maintaining the alignment of the ends of the fibers. The ferrules may be a low-melting inorganic glass, such as a lead bismuth borosilicate glass. The method and ferrules of the present invention are especially useful in splicing fibers of dissimilar thermomechanical properties.
