Direct detection of exoplanets using stellar interferometry is a major goal for astrophysics in the next decade. Planets are cool objects whose black-body radiation predominantly sits in the mid-infrared (2.0 – 12.0 µm). Furthermore, the most promising wavelength for nulling interferometry is in the astronomical L' band (3.5 – 4.1 µm) because, when compared to the infrared, the contrast between the bright host start and the faint planets becomes more favourable by several orders of magnitude.
