    摘要: An optical limiter comprises a glass backing, a glass cover, and a layer of a phase changing material placed between said glass backing and said glass cover, the phase changing material comprising a transparent matrix having embedded particles of material that changes its optical properties due to temperature induced phase change of said material. The optical properties may change from transparent to reflective, from transparent to refractive or from transparent to scattering. The phase changing material is preferably at least one material selected from the group consisting of the elements Antimony, Bismuth, Cadmium, Lead, Tin and Indium and low-melting-point alloys of two or more of these elements. Two or more layers of phase changing materials may be used in a stack configuration, with each of the phase changing materials having a unique melting temperature.

    摘要: A method for instant splicing of an optical fiber to an optical waveguide or bulk material comprises forming a nanometric conductive layer at the interface between the optical fiber and the optical waveguide or bulk material to be spliced, and applying laser radiation to the interface through the fiber optical internally or through the bulk material externally, to produce an arc discharge due to the laser light electric field. The arc discharge melts and diffuses the conductive layer to produce a permanent splice having a low optical loss.

    摘要: An optical power limiting and switching device comprises at least one plate made of transparent dielectric material, and a thin limiting solid mixture coated on one side of the plate. Upon being exposed to an optical power beam having a power level exceeding a predetermined limit power, the layer of solid mixture limits the power transmission by scattering out part of the impinging energy. When the power increases to the damage threshold, the solid mixture forms a plasma or catastrophic breakdown, damaging the solid mixture material and thereby rendering the portion of the plate surface under the impinging beam opaque to light.

    摘要: A method and apparatus of isolating a location of a fault in an optical network may include using communications traffic signals and network nodes to determine excess power losses without interrupting service or requiring additional external test equipment. A transmit optical network node is configured to measure the transmit power of multiple wavelengths of a transmitted optical signal. A receive optical network node is configured to measure the receive power of the same multiple wavelengths. Power differentials of the transmit and receive optical power for each wavelength may be calculated. Optical power losses as a function of the optical path distance between the transmit and receive optical network nodes my be determined. The data may be used to isolate the location of a fault in a passive optical network based on the differences between the optical power losses of the multiple wavelengths thereby reducing troubleshooting time and network downtime.
