Seeing the light through diamonds: Direct detection of extrasolar planet

Mikael Karlsson, Pontus Forsberg, Dimitri Mawet, Elsa Huby, and Olivier Absil

Open Access Open Access

Abstract

We have during the last 10 years been working on realizing a coronagraph consisting of a circular subwavelength grating in diamond. The design and fabrication technologies are described. The coronagraphs are installed in world leading ground-based telescopes for the search of extrasolar planets, and on sky observations are presented.
