Abstract
During the last years, LETI has developed integrated optics components for stellar interferometry using silica on silicon technology. Recent astrophysical results obtained with the three-telescope combiner IONIC3 on IOTA confirm the interest of this kind of integrated devices in terms of overall performance and stability. New combiners based on symmetric three-waveguide couplers have been theoretically studied, manufactured, and tested in laboratory in collaboration with LAOG over the H-band. Simulation et experimental preliminary results are presented and compared to asymmetric two-waveguide couplers. Applications to three- and four-telescope combination are discussed.
