Abstract

We report our progress in development of extremely coherent single mode fiber bundle arrays for high contrast imaging of extrasolar planets with TPF-C. These bundles with 32x32 fiber arrays are designed to reject scattered light while improving the image contrast by three orders of magnitude in the TPF-C visible nulling coronagraph, studied as one of the five TPF-C instrument concepts. We have developed 10x10 fiber prototype fiber bundle arrays using a combination of precision V-grooves on double side polished silicon wafers, single mode fibers and custom made lenslet arrays. The initial lab results are presented.
