Abstract

We present an experimental investigation of two-photon interference using a continuous-wave laser. Using a Mach–Zehnder interferometer, we observe two-photon coalescence and its complementary effect, Hong–Ou–Mandel interference. We also demonstrate two-photon coalescence using a Michelson interferometer. Our work paves the way for the realization of multi-photon interference in high photon loss scenarios using continuous-wave lasers.
