Abstract

We demonstrate a simple, robust, and ultrabright parametric down-conversion source of polarization-entangled photons based on a polarization Sagnac interferometer. Bidirectional pumping in type-II phase-matched periodically poled KTiOPO{sub 4} yields a measured flux of 5000 polarization-entangled pairs/s/mW of pump power in a 1-nm bandwidth at 96.8% quantum-interference visibility. The common-path arrangement of the Sagnac interferometer eliminates the need for phase stabilization for the biphoton output state.

Bright phase-stable broadband fiber-based source of polarization-entangled photon pairs

Journal Article Fan, J ; Eisaman, M D ; Migdall, A - Physical Review. A

We describe an achromatic, phase-stable, broadband source of polarization-entangled photon pairs with high spectral brightness that uses four-wave mixing in a fiber Sagnac interferometer. We achieved a polarization-entangled two-photon coincidence rate of 7 kHz per 0.5 THz (0.9 nm) of bandwidth per 300 {mu}W of average pump power. At this rate, we observed two-photon fringe interference visibilities greater than 97%, over a 10 THz ({approx_equal}21 nm) spectral range. We measured violations of Bell's inequality by more than 22 standard deviations for each of the four Bell states in less than 3 minutes per state. The high spectral brightness (26 kHzmore »« less

High-flux source of polarization-entangled photons from a periodically poled KTiOPO{sub 4} parametric down-converter

Journal Article Kuklewicz, Christopher E ; Fiorentino, Marco ; Messin, Gaetan ; ... - Physical Review. A

We have demonstrated a high-flux source of polarization-entangled photons using a type-II phase-matched periodically poled KTiOPO{sub 4} parametric down-converter in a collinearly propagating configuration. We have observed quantum interference between the single-beam down-converted photons with a visibility of 99% together with a measured coincidence flux of 300 s{sup -1}/mW of pump. The Clauser-Horne-Shimony-Holt version of Bell's inequality was violated with a value of 2.711{+-}0.017.

Generation of a pulsed polarization entangled photon pair using a Sagnac interferometer

Journal Article Shi, B -S ; Tomita, Akihisa - Physical Review. A

In this paper, we report on a scheme to generate a pulsed polarization entangled photon pair through the use of a Sagnac interferometer. To demonstrate its workability, we experimentally obtained two-photon quantum interference for the polarization variable. The main advantage of this scheme is its exceptional stability, compared to other schemes based on the interferometric technique. It does not need any active or passive techniques to stabilize the interferometer, even the instrument is exposed to a relatively turbulent environment.

Generation of ultrabright tunable polarization entanglement without spatial, spectral, or temporal constraints

Journal Article Fiorentino, Marco ; Messin, Gaetan ; Kuklewicz, Christopher E ; ... - Physical Review. A

The need for spatial and spectral filtering in the generation of polarization entanglement is eliminated by combining two coherently driven type-II spontaneous parametric down-converters. The resulting ultrabright source emits photon pairs that are polarization entangled over the entire spatial cone and spectrum of emission. We detect a flux of {approx}12 000 polarization-entangled pairs/s per mW of pump power at 90% quantum-interference visibility, and the source can be temperature tuned for 5 nm around frequency degeneracy. The output state is actively controlled by precisely adjusting the relative phase of the two coherent pumps.

Theory and experiment of entanglement in a quasi-phase-matched two-crystal source

Journal Article Ljunggren, Daniel ; Tengner, Maria ; Marsden, Philip ; ... - Physical Review. A

We report results regarding a source of polarization entangled photon pairs created by the process of spontaneous parametric downconversion in two orthogonally oriented, periodically poled, bulk KTiOPO{sub 4} crystals. The source emits light colinearly at the nondegenerate wavelengths of 810 and 1550 nm, and is optimized for a single-mode optical fiber collection and long-distance quantum communication. The configuration favors long crystals, which promote a high photon-pair production rate at a narrow bandwidth, together with a high pair probability in fibers. The quality of entanglement is limited by chromatic dispersion, which we analyze by determining the output state. We find thatmore »« less
