Two-photon interference with continuous-wave operating multi-mode coherent light



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


We report two-photon interference with continuous-wave multi-mode coherent light. We show that the two-photon interference, in terms of the detection time difference, reveals two-photon beating fringes with the visibility V = 0.5. While scanning the optical delay of the interferometer, Hong-Ou-Mandel dips or peaks are measured depending on the chosen detection time difference. The HOM dips/peaks are repeated whenever the optical delay is the same with the first-order coherence revival period of the multi-mode coherent light.
