Hong-Ou-Mandel interferometer with cavities: Theory
- Departamento de Fisica, Universidade Federal de Minas Gerais, Caixa Postal 702, 30123-970 Belo Horizonte MG (Brazil)
We study the number of coincidences in a Hong-Ou-Mandel interferometer exit whose arms have been supplemented with the addition of one or two optical cavities. The fourth-order correlation function at the beam splitter exit is calculated. In the regime where the cavities lengths are larger than the one-photon coherence length, photon coalescence and anticoalescence interference is observed. Feynman's path diagrams for the indistinguishable processes that lead to quantum interference are presented. The construction of an optical XOR gate is discussed as an application for the Hong-Ou-Mandel interferometer with two cavities.
