Paper Abstract

In a synthesized aperture implemented for stellar interferometry application, the star light usually travels by mirrors train to reach the interferometric mixing station. Using fibers the number of freedom degrees to be controlled is reduced. Parameters to be servo are the fiber length, the dispersion compensation and the polarization control. We report experimental results demonstrating the fiber length stabilization with a 5 nm accuracy, the dispersion compensation over a 300 nm spectral bandwidth (600-900 nm) and the control of polarization effects.
