Abstract: High-energy optical disinfection systems inside a commercial airplane using highly efficient, flexible, and durable side-emitting optical fibers optically coupled to high-energy UV-C laser diodes to destroy submicroscopic infectious agents and inactivate microorganisms inside the airplane. With the high-energy UV-C laser diodes optically coupled to the side-emitting optical fibers, which can be easily routed to different areas inside the airplane, the high-energy UV-C laser light emitted from the side of the optical fiber will disinfect the airplane along a wide or long swath continuously without interruption.

Abstract: An apparatus configured to function as a pluggable active optical connector that is modular with one or more channels and that converts electrical signals to optical signals and vice versa. On one side, the apparatus has a pluggable electrical interface to a line replaceable unit (LRU); on the other side the apparatus has a pluggable optical interface side to an aircraft fiber optic wiring bundle. The apparatus is pluggable to different types of LRUs including rack-mounted and bolted-down LRUs. The apparatus includes electronic and photonic components sufficient to enable electrical/optical conversion totally within a standard-sized aircraft connector. The apparatus is adaptable to various data communication protocols and has the flexibility to be used in either a single-fiber or a dual-fiber bidirectional data link.

Abstract: Systems and methods that use a passive differential optical sensor to measure the level of liquid in a reservoir (e.g., a fuel tank or other storage container). More specifically, the passive differential optical liquid level sensor solves the problem of common-mode intensity variations by employing three optical fibers that will be disposed vertically in the reservoir. The system comprises a side-emitting optical fiber having one end optically coupled to an optical source, a side-receiving optical fiber optically coupled to a first optical detector, and a total internal reflection optical fiber having one end optically coupled to the other end of the side-emitting optical fiber and another end optically coupled to a second optical detector. A computer or processor is configured to perform differential processing of the detected light and then determine the liquid level based on the differential processing results.

Abstract: A bidirectional, multi-wavelength fiber optical network that enables communication between electrical components (such as line replaceable units) at high data transmission rates. The proposed fiber optical network in accordance with some embodiments comprises a single plastic or glass optical fiber capable of transmitting data at rates faster than 1 Gbits/sec. In accordance with some embodiments, the number of fiber cables between line replaceable units onboard an airplane can be reduced by a factor of eight or more by substituting one gigabit plastic or gigabit glass optical fiber for four or more plastic or glass optical fibers.

Abstract: A method, system, and apparatus are disclosed for a ruggedized photonic crystal (PC) sensor packaging. In particular, the present disclosure teaches a ruggedized packaging for a photonic crystal sensor that includes of a hermetic-seal high-temperature jacket and a ferrule that eliminate the exposure of the optical fiber as well as the critical part of the photonic crystal sensor to harsh environments. The disclosed packaging methods enable photonic crystal based sensors to operate in challenging environments where adverse environmental conditions, such as electromagnetic interference (EMI), corrosive fluids, large temperature variations, and strong mechanical vibrations, currently exclude the use of traditional sensor technologies.

Abstract: An optical transmission device includes a tapered mixing rod that includes an optically transmissive material and has a first face, a second face, and a length. A size of the first face is based on a first number of optical fibers and a size of the second face is based on a second number of optical fibers, where the size of the first face is different from the size of the second face. The length can be selected such that light entering the first face from one of the first number of optical fibers is distributed substantially uniformly across the second face and such that light entering the second face from one of the second number of optical fibers is distributed substantially uniformly across the first face.

Abstract: A process for polishing the end face of a gigabit plastic optical fiber (GbPOF) to produce a mirror smooth surface without any defect. Smooth GbPOF end faces reduce the optical coupling loss when two plastic optical fibers are connected. The polishing process can be used to produce GbPOF end faces which are free of defects such as scratches. The polishing process involves the use of successive abrasive films having decreasing surface roughness to abrade the end of a GbPOF. More specifically, each subsequently applied abrasive film has a mean particle size which is less than the mean particle size of the previously applied abrasive film.
