Broadband frequency mode entanglement in waveguided parametric downconversion.

چکیده
We report the observation of beatings of the coincidence event rate in a Hong-Ou-Mandel interference (HOMI) between signal and idler photons from a parametric downconversion (PDC) process inside a multimode KTP waveguide. As an explanation we introduce biphotonic states entangled in their broadband frequency modes generated by waveguide mode triples and propose a suitable entanglement detection scheme.

Broadband frequency mode entanglement in waveguided PDC
Waveguided parametric downconverion (PDC) is a promising approach to realize photon pair sources for applications in quantum communication[1] or quantum imaging[2]. The mode confinement of the waveguide allows for a significant increase of the source brightness in comparison to bulk crystal setups[3]. In addition, owing to the guiding structure, a PDC process in a nonlinear waveguide will produ...

We report spontaneous parametric downconversion having an unusually wide spectral bandwidth. A collinear type-1 phase-matching configuration is employed with degeneracy near the zero group velocity dispersion frequency. With a spectral width of 1080 nm and degenerate wavelength 1885 nm, the source also emits a high flux of 3.4×10 sW photon pairs constrained to a cone of only ≈2◦ half-angle. A r...
متن کاملModal, spectral, and polarization entanglement in guided-wave parametric down-conversion
We examine the modal, spectral, and polarization entanglement properties of photon pairs generated in a nonlinear periodically poled two-mode waveguide one-dimensional planar or two-dimensional circular via nondegenerate spontaneous parametric down-conversion. Any of the possible degrees of freedom—mode number, frequency, or polarization—can be used to distinguish the down-converted photons whi...

Quantum computation and communication protocols require quantum resources which are in the continuous variable regime squeezed and/or quadrature entangled optical modes. To perform more and more complex and robust protocols, one needs sources that can produce in a controlled way highly multimode quantum states of light. One possibility is to mix different single mode quantum resources. Another ...
متن کاملMaximal-entanglement Generation via Pulsed Parametric Downconversion
Spontaneous parametric downconversion (SPDC) is the conventional source of entanglement used in most experiments. However, the state generated through SPDC using the customary phase-matching condition is maximally entangled only when a continuous-wave (cw) pump is used. In particular one sees that by decreasing the pulse length, the visibility of the interference experiments decreases. Advantag...
