Conventional optical synthesis is technologically sophisticated, but the basic principle is simple: 1D Fourier transforms between the time and frequency domains. On the other hand, control of quantum correlations of photons is of great interest in quantum optical fields. Integrating conventional optical synthesis with quantum optical technologies will pave the way for creating the arbitrary shaping of a wave packet for time-frequency entangled photons. However, the 1D Fourier transform is insufficient for understanding the behavior of the time-frequency entangled photons, namely, biphoton. Here, we expand the Fourier synthesis into high-dimensional space to deal with the quantum correlation. We first discuss the time-frequency duality of a biphotons wave packet by measuring the two-photon distributions in both time and frequency domains. We then present the manipulation of a biphoton wave packet in the time or frequency domain. Eventually, the resultant biphoton distribution in the conjugate space is modulated due to the Fourie transform relation in the 2D time-frequency space.
