Abstract

Two-photon interference of multimode two-photon pairs produced by an optical parametric oscillator has been observed with an unbalanced interferometer. The time correlation between the multimode two photons has a multipeaked structure. This property of the multimode two-photon state induces two-photon interference depending on the delay time.

Nonclassical Interference of Multimode Two-Photon Pairs with an Unbalanced Interferometer

Hayato Goto, Haibo Wang, Tomoyuki Horikiri +2 more

Nonclassical interference of multimode two-photon pairs produced by an optical parametric oscillator(OPO) has been observed using an unbalanced interferometer. The time correlation between the multimode two photons has a multi-peaked structure. The use of the multimode two-photon state has enabled the observation of the nonclassical interference at nonzero delay time.

Observation of an oscillatory correlation function of multimode two-photon pairs

Hayato Goto, Yasuo Yanagihara, Haibo Wang +2 more

An oscillatory correlation function has been observed by the coincidence counting of multimode two-photon pairs produced with a degenerate optical parametric oscillator far below threshold. The coherent superposition of the multimode two-photon pairs provides the oscillation in the intensity correlation function. The experimental data are well fitted to a theoretical curve.

Observation of time correlation of photon pairs created in photonic crystal fiber

We observe two‐photon interference of photon pairs from a photonic crystal fiber with the help of an unbalanced Mach‐Zehnder interferometer. Two‐photon interference fringes with 83% visibility, which exceed the classical limit of 50%, are obtained. The correlation time of the photon pairs is roughly estimated to be 0.2 ps

Controlling squeezing and two-photon correlations with interference in subthreshold optical parametric oscillators

A multimode theory describing the generation of photon pairs in a high-finesse Fabry-Perot cavity is presented. We also examine how interference of pairs produced with a local oscillator produces bunching and antibunching effects and also squeezing.

Two-photon interference of temporally separated photons

Heonoh Kim, Sang Min Lee, Han Seb Moon

We present experimental demonstrations of two-photon interference involving temporally separated photons within two types of interferometers: a Mach-Zehnder interferometer and a polarization-based Michelson interferometer. The two-photon states are probabilistically prepared in a symmetrically superposed state within the two interferometer arms by introducing a large time delay between two input photons; this state is composed of two temporally separated photons, which are in two different or the same spatial modes. We then observe two-photon interference fringes involving both the Hong-Ou-Mandel interference effect and the interference of path-entangled two-photon states simultaneously in a single interferometric setup. The observed two-photon interference fringes provide simultaneous observation of the interferometric properties of the single-photon and two-photon wavepackets. The observations can also facilitate a more comprehensive understanding of the origins of the interference phenomena arising from spatially bunched/anti-bunched two-photon states comprised of two temporally separated photons within the interferometer arms.
