Polarization Maintaining Coherent Fiber Bundle Array

Completed Technology Project

Project Description

Polarization Maintaining Coherent Fiber Bundle Array
Future NASA flight missions are considering passive wavefront and amplitude control in astronomical applications such as the search for exo-planets. NASA's Discovery mission proposal called out the need for a coherent 2-dimensional array of fiber bundles for this application. In this SBIR proposal we propose to develop monolithic polarization maintaining (PM) coherent fiber bundle arrays consisting of 1,600 fibers with core-to-core spacing of 80 micron with placement accuracy of < 2 micron. In Phase I we will design and develop specialty glasses and fibers and demonstrate a 2D array with 16 cores to prove the feasibility of this proposal. More »
