Abstract: A high efficiency optical combiner minimizes core region distortions in the area where fusion splicing between an input tapered fiber bundle (or any other type of “cladding-less” input fiber) and output fiber are joined. The thickness of the output fiber's glass cladding layer in the splice region is reduced (if not removed altogether) so that a core-to-core splice is formed and any necked-down region where the glass flows to join the core regions (while also joining the outer diameters) is essentially eliminated. The reduction of distortions in the core region of the splice improves the transmission efficiency between an input tapered fiber bundle and output fiber, reaching a level of about 99%. This high efficiency optical combiner is particularly well-suited for applications where a number of pump sources are combined and applied as an input to a fiber laser or amplifier.

Abstract: A method of etching silicon oxide from a trench is described which allows more homogeneous etch rates up and down the sides of the trench. One disclosed method includes a sequential introduction of (1) a hydrogen-containing precursor and then (2) a fluorine-containing precursor into a substrate processing region. The temperature of the substrate is low during each of the two steps in order to allow the reaction to proceed and form solid residue by-product. A second disclosed method reverses the order of steps (1) and (2) but still forms solid residue by-product. The solid residue by-product is removed by raising the temperature in a subsequent sublimation step regardless of the order of the two steps.

Abstract: The presence of a detectable entity within a detection volume of a microfabricated elastomeric structure is sensed through a change in the electrical or magnetic environment of the detection volume. In embodiments utilizing electronic detection, an electric field is applied to the detection volume and a change in impedance, current, or combined impedance and current due to the presence of the detectable entity is measured. In embodiments utilizing magnetic detection, the magnetic properties of a magnetized detected entity alter the magnetic field of the detection volume. This changed magnetic field induces a current which can reveal the detectable entity. The change in resistance of a magnetoresistive element may also reveal the passage of a magnetized detectable entity.
