Selective Control of Fourth-Order Interferences by means of Comb-Like Two-Photon Entangled States
Alessandro Zavatta · AIP conference proceedings · 2004
We experimentally show the selective control of fourth‐order recurrent interferences in a modified version of a Hong‐Ou‐Mandel interferometer using comb‐like two‐photon states. The comb spectral/temporal structure is obtained by inserting an etalon cavity in the signal path of an entangled photon pair obtained by pulsed spontaneous parametric down‐conversion.
