Controlling Hong-Ou-Mandel antibunching via parity governed local spectral shaping of biphoton states

Mikhail Guselnikov, Alexei D. Kiselev, Andrei Gaidash +2

We investigate into experimentally detectable effects such as the Hong-Ou-Mandel (HOM) bunching and antibunching. These regimes can be characterized using the symmetry degree param…
