| Summary: | In this paper, we realize an adjustable biphoton frequency comb and investigate its spatial quantum beating. Vector spontaneous four wave mixing processes in a piece of dispersion shifted fiber are produced by non-degenerate continuous wave pump lights with orthogonal polarizations to generate broadband biphoton states, and then a pulse shaper is used to realize the biphoton frequency comb with high-dimensional frequency-bin entanglement. The property of the biphoton frequency comb is indicated by the shape of the fringes of spatial quantum beating, which is also comb-like with a series of dips. The variations of the beating fringes show the changes of frequency bins in the comb by the setting of the pulse shaper. It can be expected that the adjustable biphoton frequency comb has great potential on high-dimensional quantum information processing and quantum communication based on the frequency degree of freedom. |
