Observation of two-photon interference with temporally non-overlapping
coherent pulses    [PDF]

Yong-Su Kim, Oliver Slattery, Paulina S. Kuo, Xiao Tang

We report experiments on two-photon interference between temporally non-overlapping weak coherent pulses. While the single-photon interference is washed out, the two-photon interference shows a Hong-Ou-Mandel dip with visibility of $0.50\pm0.09$, which shows that the two-photon classical interference does not require temporal overlapping between optical pulses.
