Measuring the biphoton temporal wave function with polarization-dependent and time-resolved two-photon interference.

چکیده
We propose and demonstrate an approach to measuring the biphoton temporal wave function with polarization-dependent and time-resolved two-photon interference. Through six sets of two-photon interference measurements projected onto different polarization subspaces, we can reconstruct the amplitude and phase functions of the biphoton temporal waveform. For the first time, we apply this technique to experimentally determine the temporal quantum states of the narrow-band biphotons generated from the spontaneous four-wave mixing in cold atoms.

Duality between partial coherence and partial entanglement
Entangled-photon pairs ~biphotons! generated by spontaneous optical parametric down-conversion exhibit a number of properties that are analogous to those of ordinary photons generated by incoherent sources. The spatial pump-field distribution and the two-particle wave function in the biphoton case play the respective roles of the source intensity distribution and the second-order coherence func...
متن کاملBiphoton Generation in a Two-Level Atomic Ensemble
We have theoretically studied the space-time entangled biphoton state generated from a two-level atomic system. In the photon counting measurement, the two-photon coincidence counting rate is a damped oscillation. The oscillation period is determined by the effective Rabi frequency and the damping rate is determined by the linewidth of the inhomogeneous-broadened ground state and the dipole dep...
متن کاملTime-Resolved Two-Photon Quantum Interference
The interference of two independent single-photon pulses impinging on a beam splitter is analysed in a generalised time-resolved manner. Different aspects of the phenomenon are elaborated using different representations of the single-photon wave packets, like the decomposition into single-frequency field modes or spatio-temporal modes matching the photonic wave packets. Both representations lea...

Background: Near infrared spectroscopy imaging is one of the new techniques used for investigating structural and functionality of different body tissues. This is done by injecting light into the medium and measuring the photon intensity at the surface of the tissue.Method: In this paper the different medical applications, various imaging and simulation techniques of NIRS imaging is described. ...
متن کاملLab2: Single Photon Interference
The wave-particle duality of light was verified by multi and single photon interference both through Young’s double slit and Mach-Zehnder interferometer. In these two sets of experiments, the interference in the single photon level is the same as that at multi photons level with long enough exposure time. In the Mach-Zehnder interferometer, the “whichpath” information can be identified by measu...
