Parallel Optical Backplane Interconnections for Avionics and High-Performance Computers

We propose to develop ruggedized optical connector arrays for interconnection of electronic processing modules through parallel fiber ribbon optical backplanes. Computer manufacturers consider optical backplanes the inevitable next step in interconnections and optical connector arrays to be the most-needed component. Arrays of vertical-cavity surface-emitting lasers (tradenamed LASE-ARRAY¿ by Photonics Research Incorporated) are ideally suited for the transmitters and PRI will utilize its world leadership in this field-to optimize LASE-ARRAY¿ for optical backplanes. In Phase I we will: 1) specify the performance requirements for the optical backplane components: microlaser arrays, fibers, connectors, detectors; 2) survey the mechanical and micro-optic "tools" available for optical connector arrays; 3) design LASE-ARRAY¿s for multimode fiber backplanes 4) design connector arrays for the optical backplanes; and 5) develop the Phase II plan for demonstration and commercialization. Assembly of the technical team for commercialization of optical backplane interconnects has begun at PRI and will continue throughout Phases I and II. Fiber-optic sensor networks, optical backplanes and local area networks are most immediately needed in the avionics industry, hence our program targets these applications.
