Second-order temporal interference of two independent light beams at an asymmetrical beam splitter

Liu Jianbin^{1, 2, †}, Wang Jingjing^{1, 2}, Xu Zhuo^{1, 2}

(color online) The scheme for the second-order interference of two independent light beams at an asymmetrical BS. Here, and are two independent light sources, ABS is an asymmetrical beam splitter, D₁ and D₂ are two single-photon detectors, and CC is a two-photon coincidence counting detection system.
