Abstract: 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.

Abstract: In accordance with an exemplary embodiment of the present invention, an optical interleaver/deinterleaver includes a substrate having at least one window therein. The interleaver/deinterleaver further includes a first optical waveguide and a second optical fiber, which are disposed over a substrate. The first and second optical waveguides are coupled together at at least two locations to form optical couplers at each of the locations. The first optical waveguide has a first length between the two locations, and the second optical waveguide has a second length between the two locations wherein the first length is smaller than the second length. Illustratively, the first optical waveguide is disposed over the window, so that the window is along the first length of the first optical fiber.

Abstract: To make an overclad fiber optic coupler, the bare regions of a plurality of optical fibers are positioned within a glass capillary tube. The midregion of the tube is then collapsed and stretched to cause coupling between the fibers. To obtain desirable coupling characteristics, the fibers must be situated in the glass tube bore in side-by-side fashion such that the cross-sectional configuration of the fibers constitutes a given geometrical array. To ensure that the fibers are properly positioned within the glass tube, they are fed to that tube from a plurality of guide tubes, the ends of which are retained adjacent to the end of the glass tube in side-by-side fashion in the given geometrical array.
