| Research Abstract |
I developed an optical integrated optics in order to obtain a high-contrast image by removing the effect of atmospheric turbulences for direct imaging of extra-solar planets from the ground. The characterization of the developed 18-input, 81-output integrated optics shows that it can act as an interferometric beam combiner with phase shifters. This 18-beam 81-output integrated optics is one of the most complex integrated optics for astronomy.
