    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 planar, rigid substrate made from a porous, inorganic material coated with cationic polymer molecules for attachment of an array of biomolecules, such as DNA, RNA, oligonucleotides, peptides, and proteins. The substrate has a top surface with about at least 200 to about 200,000 times greater surface area than that of a comparable, non-porous substrate. The cationic polymer molecules are anchored on the top surface and in the pores of the porous material. In high-density applications, an array of polynucleotides of a known, predetermined sequence is attached to this cationic polymer layer, such that each of the polynucleotide is attached to a different localized area on the top surface. The top surface has a surface area for attaching biomolecules of approximately 387,500 cm2/cm2 of area (˜7.5 million cm2/1×3 inch piece of substrate). Each pore of the plurality of pores in the top surface of the substrate has a pore radius of between about 40 Å to about 75 Å. Not only does the cationic coating in and over the pores of the substrate greatly increase the overall positive charge on the substrate surface, but also given the size of the pores provides binding sites to which biomolecules can better attach.

    摘要： A method of protecting a silica-containing article used in the manufacture of an optical fiber includes the step of applying to the silica-containing article a protective layer that facilitates removal of particulates that deposit on the protective layer and that ablates during or can be removed before subsequent processing of the silica-containing article. An intermediate product used in the manufacture of an optical fiber and protected against break-inducing particulates includes a silica-containing article, and a protective layer that facilitates removal of particulates that have deposited on the protective layer and that can be ablated during or removed before subsequent processing of the intermediate product.

    摘要： A method of manufacturing a silica-containing article used in the manufacture of an optical fiber includes the steps of applying to the silica-containing article a protective layer, and then transporting the coated article to a second factory for further processing. The layer facilitates ease of removal of particulates that deposit on the protective layer. The layer preferably ablates during, or can be readily removed subsequent to, further processing of the silica-containing article. Any intermediate product used in the manufacture of an optical fiber, for example, a core blank, core cane segment, consolidated preform, etc. may be readily shipped between various factories because the articles are protected against break-inducing particulates by the protective layer.
