Achromatic modulators and hybrid beam combiners for astrophotonics

We present our work on achromatic beam combiners to achieve wide band interferometry, using electro-optic devices. We also present our developments in hybrid integrated optics interferometers coupling passive devices but allowing sharp bending radius waveguides and active devices, allowing phase modulation in lithium niobate channel waveguides. These systems have been developed for visible applications, in the context of LITHIUM cubesat project and FIRST 9 channel beam combiner for FIRST/SUBARU telescope.
