    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： An optical signal limiter is provided for limiting transmission of a continuous wave optical signal that exceeds a preselected threshold power level. The limiter includes a body having input and output ends that is formed at least in part from a material having a negative thermal index coefficient of between about −0.5×10−4 °C.−1 and −4.0×10−4 °C.−1 and an absorption coefficient of between 1.0 to 5.0 dB/cm at wavelengths between 980-1650 nm. The limiter also includes collimating fibers mounted on the input and output ends to minimize low power signal losses across the limiter body. It may be installed at a junction between two optical fibers and is preferably formed from a curable adhesive having the aforementioned negative thermal index coefficient to obviate the need for separate bonding materials and joining steps during the installation of the limiter. The optical limiter is reusable and with a recovery time of 1-5 milliseconds advantageously prevents power surges in optical circuits from damaging sensitive optical components by limiting the amplitude of such surges within 0.2-0.5 milliseconds.

    摘要： A method is provided for sealing one or more fill holes (42, 44) in a glass plate (14) of an organic dye solar cell and other glass packages by covering the hole(s) (42, 44) with a laser absorbing glass patch (52, 54). The outer perimeter of the glass patch (52, 54) is melted with a laser such that the outer perimeter of the glass patch (52, 54) is hermetically sealed to the glass plate (14). Another method is provided in which the fill holes (42, 44) are covered with a glass patch (52, 54) having a loop of absorbing frit around the outer periphery thereof. The loop of frit is melted with a laser such that the outer perimeter of the glass patch (52, 54) is hermetically sealed to the glass plate (14). In both process, the laser beam is either (1) formed into a loop shape beam around the perimeter of the glass patch (52, 54) or (2) quickly travels around the perimeter of the glass patch (52, 54) in such a manner that the loop of frit or the entire perimeter of the absorbing glass patch (52, 54) is uniformly heated to substantially the same temperature to minimize thermal stresses crated during heating and sealing.

    摘要： An accelerated radiation damage testing method for an optical sample includes disposing the optical sample inside or external to an optical cavity and injecting a predetermined number of light pulses into the optical cavity at a selected wavelength and at spaced intervals. Each light pulse injected into the optical cavity produces a train of pulses which are focused on the optical sample. The method further includes allowing each light pulse in the optical cavity to decay to a selected value and determining a change in a selected optical property of the optical sample after the optical sample has been exposed to a predetermined number of pulses.
