    摘要： A device amplifies light at wavelengths in the vicinity of 1420-1530 nm, using thulium doped silica-based optical fiber. This wavelength band is of interest as it falls in the low-loss optical fiber telecommunications window, and is somewhat shorter in wavelength than the currently standard erbium doped silica fiber amplifier. The device thus extends the band of wavelengths which can be supported for long-distance telecommunications. The additional wavelength band allows the data transmission rate to be substantially increased via wavelength division multiplexing (WDM), with minimal modification to the standard equipment currently used for WDM systems. The host glass is directly compatible with standard silica-based telecommunications fiber. The invention also enables modified silicate based amplifiers and lasers on a variety of alternative transitions. Specifically, an S-band thulium doped fiber amplifier (TDFA) using a true silicate fiber host is described.

    摘要： This invention pertains to a hollow core photonic band gap chalcogenide optical glass fiber and to a fabrication method for making the fiber. The fiber, which is 80-1000 microns in outside diameter, is characterized by a solid glass circumferential region and a structured region disposed centrally within the solid region, the structured region includes a hollow core of 1 micron to several hundreds of microns in diameter surrounded by a plurality of parallel hollow capillaries extending parallel to the core, the core being centrally and longitudinally located within the fiber. Ratio of open space to glass in the structured region is 30-99%. The fabrication method includes the steps of providing a mold, placing chalcogenide micro-tubes around the mold, stacking chalcogenide micro-canes around the stacked micro-tubes, fusing the micro-tubes and the micro-canes to form a preform, removing the mold and drawing the preform to obtain the fiber. In an alternative fabrication method, the fiber is made by extruding flowing chalcogenide glass through suitably made plate to form a preform and then drawing the preform to form the fiber.

    摘要： An apparatus for exercising the muscles of the lumbar region of a subject's back includes a seat, a vertical support member to which the back end of the seat is attached so that the centerline extending from the from the front to the back of the seat forms an angle with the vertical member in the range of 65 to 75 degrees and with the front end of the seat being inclined downward to the surface on which the vertical support member stands, a base attached to the bottom end of the vertical support member, a cylindrical roller pad that is rotatably mounted to the vertical support member at a position above the seat, a knob that is adjustably mounted to the vertical support member, and a hand-held weight which the subject grasps and holds near the subject's body while performing the strengthening exercises. In a first embodiment, these entail the subject sitting on the seat and assuming a first position with subject's upper torso bent over so as to be proximate the thighs and a hand-held weight grasped and held near the subject's chest. The subject then moves to a second position by raising the upper torso while continuing to hold the hand-held weight near the subject's chest and keeping the pelvis and sacrum in contact with the pad. A preferred angular range of motion of the subject's back while so exercising is approximately seventy-two degrees. In a second embodiment, the exercises entail the subject standing with a hand-held weight near the hip and with the sacrum against the knob so as to keep the hips and pelvis from moving while the subject does lateral, upper body bending exercises.
