Demonstration of Temporal Distinguishability of Three and Four Photons with Asymmetric Beam Splitter

Abstract

By using an asymmetric beam splitter, we observe the generalized Hong-Ou-Mandel effects for three and four photons, respectively. Furthermore, we can use this generalized Hong-Ou-Mandel interferometer to characterize temporal distinguishability.
