Abstract

In this paper we present a status report of our single mode (SM) fiber work for interferometry. In the past two years two experiments have been carried out by our group at the Maui Space Surveillance Site linking two 1.2 meter telescopes using single mode fibers and obtaining white light fringes on (alpha) Bootis. During this experiment we were able to measure coupling efficiency between atmospherically degraded images, D/r₀ approximately 10, and the fibers using a tip/tilt mirror on each of the two telescopes. We compared our results with theoretical calculations. Furthermore we will present some of the experimental result and 'lesson learned'. We will also present the progress on our multi-core single mode fibers program. We have a first four core prototype under test and preliminary results will be presented.
