The ST-connector is the standard Navy single fiber connector. It is a quick-release fiber connector which makes it easy to connect and install but the quick release nature of the coupling makes it very sensitive to severe vibration. We propose a novel coupling system that will be incorporated into the ST-connector, which will significantly reduce its sensitivity to vibration. Our coupling system will include diffractive optics and proven coupling techniques. The beam will be allowed to expand as it emerges from the first fiber and a collimating diffractive optic will be utilized to collimate this expanded beam and a focusing diffractive optic will be utilized to focus the beam into the second fiber. The expanded beam will reduce system sensitivity to misalignment which can be caused by vibration. In addition, the diffractive optic elements will be specifically designed to reduce sensitivity to vibration.

The objectives of this proposed Phase II project are to develop the appropriate optics for an 8 wavelength CWDM system and demonstrate both the multiplexed data link and the integration of the link with an aircraft actuator. Fly-by-light (FBL) systems have been the subject of research for many years; however, there are still several hurdles to overcome before FBL systems can provide the next advance in flight control technology. One of the main difficulties with current proposed FBL systems is the large number of fibers required. In order to reduce the number of fibers, coarse wavelength division multiplexing (CWDM) can be used to increase the signal capacity of individual fibers. The Phase I effort resulted in an architecture design capable of decreasing the number of fibers from 1190 to 210 when using a CWDM system with 8 wavelengths. Digital Optics Corporation will develop and demonstrate the necessary components for a CWDM based sensor network for FBL applications. New CWDM modules will be designed and fabricated and assembled with the necessary active components and optical sensors in order to demonstrate a complete optical data link. Partnering with HR Textron, this CWDM data link will be integrated with an aircraft actuator.
