| Patent application number | Description | Published |
|---|---|---|
| 20090279835 | Single-Mode Optical Fiber Having Reduced Bending Losses - A single-mode optical fiber includes a central core, an intermediate cladding, a depressed trench, and an external optical cladding. The central core has a radius r | 11-12-2009 |
| 20090279836 | Bend-Insensitive Single-Mode Optical Fiber - A single-mode optical fiber includes a central core, an intermediate cladding, a depressed trench, and an external optical cladding. The central core has a radius r | 11-12-2009 |
| 20100118388 | Amplifying Optical Fiber and Method of Manufacturing - Disclosed is an amplifying optical fiber having a central core and an optical cladding surrounding the central core. The central core is based on a silica matrix that includes nanoparticles, which are composed of a matrix material that includes doping ions of at least one rare earth element. The amplifying optical fiber can be employed, for example, in an optical amplifier and an optical laser. | 05-13-2010 |
| 20100290781 | Microbend-Resistant Optical Fiber - Disclosed is an improved, single-mode optical fiber possessing a novel coating system. When combined with a bend-insensitive glass fiber, the novel coating system according to the present invention yields an optical fiber having exceptionally low losses. | 11-18-2010 |
| 20110116160 | Rare-Earth-Doped Optical Fiber Having Small Numerical Aperture - The present invention embraces an amplifying optical fiber having a central core adapted to convey and amplify an optical signal and a cladding that surrounds the central core to confine the optical signal conveyed in the central core. The central core is formed of a core matrix in which nanoparticles are present. The nanoparticles themselves include a nanoparticle matrix and rare-earth-dopant elements. The core matrix may also include one or more additional dopants (i.e., in addition to nanoparticles). The amplifying optical fiber possesses a small numerical aperture and is suitable for use in high-pump-power applications without a degraded gain shape. | 05-19-2011 |
| 20110135264 | Bend-Insensitive Single-Mode Optical Fiber - The present invention embraces a single-mode optical fiber that, at a wavelength of 1550 nanometers, has bending losses of 0.15 dB/turn or less for a radius of curvature of 5 millimeters. | 06-09-2011 |
