Abstract
In the frame of ESA's DARWIN mission technological studies, Alcatel Space, supported by ESA, is designing and manufacturing a nulling interferometer whose aim is to demonstrate in laboratory the extinction of a point source with a stable nulling ratio of 10^-6. The results of the first integration phase of this breadboard is presented in this paper.
