摘要: Siloxane compounds formed by the reaction of a hydridosiloxane with vinylsiloxane are employed in a wide variety of uses, e.g., coatings for optical fibers and flexible layers for touch screen cathode ray tubes. These siloxane materials are substantially improved through treatment with a lower alkene such as ethylene to prevent hydrogen evolution and undesirable crosslinking.

摘要: Disclosed is a planar optical waveguide that is manufacturable by the compression molding or embossing of a multilayer film of polymeric material. In one embodiment, the waveguide comprises a core layer of relatively high refractive index included between cladding layers of lower refractive index. The waveguiding channels are bounded by regions where the cladding layers are in contact and from which core material has been excluded.

摘要: Molding optical components from a mold that is produced using the same type of optical fibers that will be interconnected by the optical components. The outer diameter of a silica optical fiber varies only by approximately .+-.1 micron and the outer surface of a silica optical fiber has an optical finish. Thus by using optical fiber to fabricate molds, molds can be produced which have the required accuracy and finish for the production of optical components. The outer coating of the optical fibers used to fabricate the mold is only removed within and in close proximity to a combination region in a splitter/combiner resulting in the capability to pigtail optical fibers attached to a splitter/combiner molded from the resulting mold.

摘要: A molded polymeric resin-filled coupler comprising two low-refractive index plastic molded subassemblies. One subassembly has an optically finished mixing region, with a channel that has a V shaped lower portion. The mixing region subassembly is covered with a lid subassembly of the same material as the mixing region subassembly. During assembly, optical fibers are inserted into the mixing region subassembly which is then filled with a high index material to form a high-refractive index waveguide core region in the channel. The molded low-refractive index subassemblies provide a waveguide cladding around the high-refractive index waveguide core. Low cost is attained by utilizing optically finished metal molds to produce the subassemblies resulting in an optically finished mixing region and lid subassemblies without the need to polish each subassembly.

摘要: An optical coupler having an optical core in which a small concentration of refractive microparticles has been added to a suspension material of the optical core. The result is that light from an optical source is bent slightly by the refractive effects of the microparticles and is coupled into the higher order of modes over a relatively short distance within the optical core. These microparticles are closely matched to the index of refraction of the suspension material resulting in smaller deflection angles and fewer reflections. In addition, these microparticles match the specific gravity of the suspension material such that they do not settle out of a suspension while the optical core material is being hardened from a semi-liquid state.

摘要: Optical fibers having ultraviolet-cured coatings and reduced optical transmission losses are produced. An ultraviolet-absorbing material is incorporated in at least one coating layer. This reduces damage in the glass fiber due to the ultraviolet-curing radiation, while still allowing rapid curing of the coating. Single layer coatings and dual layer coatings are described. A single layer coating having reduced microbending losses due to partial curing of the inner portion of the coating is also described.

摘要: An improved process for extruding plastic optical fiber without the need to prepare a preform is provided. Specifically, it was discovered that conventional extrusion techniques, e.g., screw extruders, tended to introduce an undesirable amount of particulate contaminants which increased the loss of the drawn fiber. To overcome this problem, the invention substantially reduces the number of mechanical interactions that contribute to such contamination. The process of the invention does so by using fluid pressure, instead of, e.g., screw extruders, to induce polymer flow. The process also controls the flow characteristics of the polymer, or halts the flow altogether, without mechanical controls. Specifically, the temperature of the sections through which the polymer flows is controllably adjusted, such that it is possible to bring the polymer to a desired flow rate or even to a solid state to provide a plug.

摘要: Finishing an end of a plastic optical fiber by ablating the end of the plastic optical fiber by utilizing an Excimer laser so that the end of the optical fiber can be used in a optical connector. A high powered ultraviolet beam of light from the laser is absorbed by the end of the fiber and ablates the first few microns of the end face of the fiber. This process removes residual cracks and fissures to flatten the end of the fiber for use in the optical connector. The optical fiber is then ready to make a low loss interface with a source, a detector, or another optical fiber.

摘要: A continuous extrusion process is provided capable of producing graded index plastic optical fiber at commercially useful speeds, e.g., at least 1 m/sec for 250 &mgr;m outer diameter fiber. Moreover, it is possible to predict the refractive index profile of the fiber, prior to actual fabrication, by performing a finite element analysis using various parameters of the extrusion process. Such prediction allows one to tune the parameters of the process to obtain a desirable outcome, while avoiding the need for substantial trial and error with the extrusion equipment.

摘要: Depolarization of light by utilizing a small concentration of refractive or diffractive microparticles in an optical core of an optical coupler that is coupling light from polarized source to a polarization type optical switch such as a ferroelectric liquid crystal. The result is that light from the laser is bent slightly by either the refractive or diffractive effects of the microspheres which causes scattering; and as a consequence, the light is depolarized in a relatively short distance within the optical core before reaching the liquid crystal switch. The microparticles maybe closely matched to the index of refraction of the core material resulting in smaller deflection angles and lower reflections. In addition, these microparticles match the specific gravity of the core material such that they do not settle out of suspension while the core material is being hardened from a semi-liquid state.
