Conditions for two-photon interference with coherent pulses
Yong-Su Kim, Oliver T. Slattery, Paulina 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±0.09, which shows that the two-photon classical interference does not require temporal overlapping between optical pulses.
