The complementarity relation between the spectral distinguishability of frequency-shifted photonic wave packets in a Hong–Ou–Mandel interferometer and the resulting interferogram’s visibility is studied. Experimental definition of K, the distinguishability parameter, and V, the interferogram’s single-photon visibility, is proposed and tested for the K2+V2≤1 complementarity inequality. The results show that the spectral distinguishability is, indeed, complementary to the visibility and that the quantum aspect of the two-photon interference phenomenon can be examined by employing weak coherent states.
