Abstract: A method for modifying a low-cost small form factor pluggable optical-electrical bidirectional transceiver (hereinafter “SFP transceiver”) by converting the SFP transceiver into a dual-in-line package. Such conversion enables the SFP transceiver to be soldered directly on a printed circuit board of a line replaceable unit of an avionics system, thereby eliminating the concern that the SFP transceiver may become detached due to vibration during aircraft operation. The method also includes a sealing process to protect the contact pads on the SFP transceiver, thereby eliminating any concern that the contact pads could corrode due to long-term moisture and humidity exposure. The product of the method is a ruggedized SFP transceiver capable of withstanding the rigors of operating in a harsh avionics environment onboard an aircraft.

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: An optical subassembly includes a housing, a laser package, and first and second end sections of side-emitting optical fiber. The housing defines first, second, and third channels which extend from a central space. The laser package is affixed to the third channel and comprises an edge-emitting UV-C laser diode disposed in the central space and having first and second edges. The first end section of side-emitting optical fiber is retained in the first channel and has a first end face which confronts the first edge. The second end section of side-emitting optical fiber is retained in the second channel and has a second end face which confronts the second edge. The housing further defines a fourth channel which extends from the central space. The optical subassembly further includes a transparent window seated in an opening of the fourth channel.

Abstract: A fuel sensing system utilizes non-contact plastic optical fiber (POF) to optically sense the level of liquid fuel in a fuel tank. In one implementation, the fuel level sensing system includes the following elements: (i) a high-speed and high-power red laser diode; (ii) an ultra-high-sensitivity photon-counting avalanche photodiode; and (iii) a large-diameter and large-numerical-aperture graded-index POF. The fuel level is sensed when the avalanche photodiode first detects impinging light reflected by the POF end face and then detects impinging light reflected by the fuel surface in response to emission of a laser pulse by the red laser diode. A time delay detection circuit calculates the time interval separating the respective times of arrival. A fuel level calculator calculates the fuel level based on the time interval provided by the time delay detection circuit.

Abstract: A ruggedized hermetic optical fiber connector and methods for fabricating such an optical fiber connector which has both durability and hermeticity. The hermetic optical fiber connector is epoxy free and hermeticity is achieved by a sequence of high-temperature soldering steps with a proper soldering temperature hierarchy. The design of the hermetic optical fiber connector is universal for both glass optical fiber and plastic optical fiber connections. In addition, the universal hermetic optical fiber connector is ruggedized to withstand harsh avionics environments without incurring optical fiber damage inside the connector.
