摘要： Novel attenuators for use in single-channel applications are disclosed. The attenuators include a crosslinked siloxane copolymer composition, prepared by crosslinking a vinyl-terminated dimethylsiloxane-diphenylsiloxane copolymer with a silane crosslinking agent in the presence of a platinum catalyst. The crosslinked copolymer overlies a portion of a side-polished optical fiber or tapered optical fiber. Optical energy propagating through the fiber can be extracted when the refractive index of the crosslinked material is varied about that of the optical fiber. The attenuators are useful in single-channel applications, such as the ever-popular 1310 nm and 1550 nm wavelengths.

摘要： Novel polymer compositions for controlling or correcting dispersion mismatch between the composition and a side-fiber polished optical fiber are disclosed. The polymer compositions contain an infrared absorbing dye having an absorption maximum from about 900 to about 1200 nm and and a polar olefin copolymer containing monomers which are formed from polar olefins having an ester, benzene, or halogen substitutent attached. A method for controlling the dispersion exhibited by the novel polymer compositions is also disclosed. The method includes forming the polymer composition over an exposed surface of an optical fiber. Dispersion is controlled by controlling the amount of dye present in the polymer composition. Also disclosed is an optical device from which improvements in the uniformity of spectral response and performance are observed across a wavelength band. The optical device includes the polymer composition formed over an optical fiber. Variable optical attenuators, switches, and couplers can be designed which incorporate the polymer compositions. The invention is particularly useful in the 1500-1600 nm wavelength band.

摘要： Controllable fiber optic attenuators and attenuation systems are disclosed for controllably extracting optical energy from a fiber optic, and therefore attenuating the optical signal being transmitted through the fiber optic. In one aspect, material is removed from a portion of the fiber optic, thereby exposing a surface through which optical energy can be extracted. The portion of the fiber is suspended between two support points, and a controllable material is formed over the surface for controllably extracting optical energy according to a changeable stimulus applied thereto, which affects the refractive index thereof. In one embodiment, the changeable stimulus is temperature, and a controllable heating/cooling source can be provided in the attenuator for control of the attenuation. The limited amount of thermal contact between the suspended, side-polished portion of the fiber optic and the controllable material to surrounding structures offers a more predictable response, and improved response time. The controllable material, in one embodiment, may be a dispersion controlled (e.g., matched) polymer, offering uniform spectral characteristics of attenuation across a wavelength band of interest.

摘要： Chiral organic polymers doped with or appended by nonlinear optical dyes are disclosed. The use of chiral polymers produces a more stable noncentrosymmetric environment for the dye molecules resulting in unexpectedly long relaxation times as compared with previously used organic polymers. In addition, the NLO/chiral polymer materials exhibit high electro-optical coefficients (r33), high nonlinear optical coefficients (d33), improved long-term thermal stability, and at the same time retain the processing advantages associated with organic polymers. Thus, the present NLO/chiral polymer materials are extremely well-suited for use in second-order nonlinear optical and optoelectronics devices.

摘要： Novel dye/polymer compositions are disclosed, which when used in connection with fiber optic devices, provide a uniform spectral response across a broadband wavelength region. The dye/polymer compositions contain an infrared absorbing dye having an absorption maximum from about 900 to about 1300 nm. One or more polar olefin copolymers containing monomers derived from polar olefins having an ester, benzene, or halogen substitutent attached, is/are chemically bonded to the dye. Optionally, a detached polar olefin copolymer may be blended with the dye-appended copolymer. Also disclosed is a broadband optical device comprising the novel dye/polymer compositions formed over an optical fiber. Improvements in the uniformity of spectral response and performance are observed across a wavelength band. Variable optical attenuators, switches, shutters, and couplers can be designed which incorporate the dye/polymer compositions. The invention is particularly useful in the 1500-1700 nm wavelength band.
