Abstract

We introduce an efficient method for fully characterizing multimode linear-optical networks. Our approach requires only a standard laser source and intensity measurements to directly and uniquely determine all moduli and non-trivial phases of the matrix describing a network. We experimentally demonstrate the characterization of a 6x6 fiber-optic network and independently verify the results via nonclassical two-photon interference. (C) 2013 Optical Society of America
