Abstract

Principally because single-mode fibers are perfect spatial filters, they have great potential for ground-based interferometry. The author of this paper has recently shown how a novel multiple-core design can enhance the overall efficiency of a SM fiber many-fold when the fiber is coupled to atmospherically degraded wavefronts. We present theoretical results on the possible enhancement of signal-to-noise ratios in image reconstruction with interferometers using such fibers with a multiple-core geometry. Our results have strong implications for the feasibility of an all-fiber interferometry concept, both on the ground and in space.
