Over the last several decades, quantum entanglement has been intensivelystudied for potential applications in quantum information science. TheHong-Ou-Mandel (HOM) dip is the most important test tool for direct proof ofentanglement between paired photons, whose coincidence detection results inanticorrelation due to photon bunching on a beam splitter. Althoughanticorrelation is due to destructive quantum interference between pairedphotons, a wavelength-sensitive interference fringe has never been observed inany HOM-type experiments. Here, a typical HOM dip is investigated for entangledphoton pairs generated by parametric down conversion processes (SPDC) tounderstand fundamental physics of anticorrelation. In addition, a purecoherence optics-based Hong-Ou-Mandel scheme is proposed and analyzed forgeneral understanding of anticorrelation in an interferometric system. Thisstudy sheds light on deterministic quantum correlation control and opens thedoor to potential applications of on-demand quantum information science.
