Abstract
Evanescent coupled waveguides could be used to build multipartite inferometeros, which create an optical quantum state generator. The characterization of these integrated photonic devices needs a large effort and experimental expertise. We develop a method to reduce the measurement steps rapidly by using classical laser light. We show the application of this technique on a laser written W-state generator of the order N = 8.
