20090034923 - Fiber optic cables suitable for automated preconnectorization: Fiber optic drop cables are disclosed that are suitable for automated preconnectorization. In one embodiment, an optical waveguide is disposed in a buffer tube that has two strength components disposed on opposite sides thereof and a plurality of strength members. The plurality of strength members are disposed at a plurality... Agent: Corning Incorporated
20090034922 - Optical fiber cable: It is an object of the present invention to provide an optical fiber cable which can reliably prevent increased transmission loss due to damage of the optical fiber as a result of the egg-laying behavior of cicadas. The cable includes at least an optical fiber 1, tension members 6 and... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.C.
20090034924 - Photonic devices having degenerate or split spectral band edges and methods for using the same: Provided herein are photonic devices configured to display photonic band gap structure with a degenerate or a split band edge. Electromagnetic radiation incident upon these photonic devices can be converted into a frozen mode characterized by a significantly increased amplitude, as compared to that of the incident wave. The device... Agent: Orrick, Herrington & Sutcliffe, LLPIPProsecution Department
20090034925 - Optical fibers and optical fiber devices with total dispersion greater than material dispersion: Disclosed are optical fiber devices incorporating optical fibers with total dispersion greater than material dispersion, and with preferred dispersion values less than +50 ps/nm-km. The desired dispersion values are obtained when light resides substantially in a single higher order mode (HOM) of the fiber, typically the LP02 mode. The optical... Agent: Furukawa Electric North America, Inc. (formerly Fitel Usa Corp.)
20090034926 - Holey fiber and method of manufacturing the same: A holey fiber has a core region, a cladding region surrounding the core region, air holes arranged around the core region, and a connection section extending from at least one end portion of the holey fiber. A refractive index of the core region in the connection section is higher than... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, P.C.
20090034927 - Photonic crystal fibers and medical systems including photonic crystal fibers: In general, in one aspect, the disclosure features a system that includes a flexible waveguide having a hollow core extending along a waveguide axis and a region surrounding the core, the region being configured to, guide radiation from the CO2 laser along the waveguide axis from an input end to... Agent: Fish & Richardson P.C.
20090034928 - optical waveguide film, optical substrate, and methods for manufacturing the same: An optical waveguide film includes a clad layer having an adhesive function; and a core layer covered by the clad layer.... Agent: Akerman Senterfitt
20090034929 - Fiber termination block with splitters: The present invention relates to the management of cables extending to and from fiber termination blocks with sliding fiber adaptor modules within a fiber distribution frame. The blocks include a splitter chassis and fiber optic splitters mounted within the chassis.... Agent: Merchant & Gould PC
20090034930 - Polymeric compositions comprising quantum dots, optical devices comprising these compositions and methods for preparing same: The present invention relates to a polymeric composition of matter. The composition includes at least one polymer matrix and plurality of quantum dots distributed therein. The polymer may be a perfluorocyclobutane polymer having high optical transmission at telecommunications wavelengths. The quantum dots may include cap compounds to increase the solubility...
