Wideband nonlinear frequency conversion with OAM fiber

Boyin Tai, Patrick Gregg, Lars Søgaard Rishøj +1 more

We propose >99% efficient wideband frequency conversion between visible and telecommunication bands for quantum networks and single-photon detection, enabled by the enhanced phase matching capabilities offered by intermodal Bragg scattering in OAM fibers.

Highly efficient frequency downconversion at the single photon level

Sebastian Zaske, Andreas Lenhard, Christoph Becher

We here report on work achieving a conversion efficiency that is at least 40 times higher compared to similar experiments that have used optical powers at the single photon level.

High-efficiency frequency conversion in the single-photon regime

Alex S. Clark, Shayan Shahnia, Matthew J. Collins +2 more

In this Letter we demonstrate frequency conversion in the single-photon regime through Bragg-scattering four-wave mixing with near-unit efficiency in a 750 m long commercially available dispersion-engineered highly nonlinear fiber, where all photons and pump laser frequencies are in the low-loss telecommunications band. We achieve 99.1%±4.9% downconversion and 98.0%±5.0% upconversion of photons by 12 nm using a weak coherent state with an average input of 0.27 photons per detection gate window.In this Letter we demonstrate frequency conversion in the single-photon regime through Bragg-scattering four-wave mixing with near-unit efficiency in a 750 m long commercially available dispersion-engineered highly nonlinear fiber, where all photons and pump laser frequencies are in the low-loss telecommunications band.

Resource-efficient frequency conversion for quantum networks via sequential four-wave mixing

T. A. Wright, Charlotte Parry, O. R. Gibson +2 more

We report a resource-efficient scheme in which a single pump laser was used to achieve frequency conversion by Bragg-scattering four-wave mixing in a photonic crystal fiber. We demonstrate bidirectional conversion of coherent light between S r + 2 P 1 / 2 → 2 D 3 / 2 emission wavelength at 1092 nm and the telecommunication C band with conversion efficiencies of 4.2% and 37% for up- and down-conversion, respectively. We discuss how the scheme may be viably scaled to meet the temporal, spectral, and polarization stability requirements of a hybrid light–matter quantum network.We report a resource-efficient scheme in which a single pump laser was used to achieve frequency conversion by Bragg-scattering four-wave mixing in a photonic crystal fiber.
