Frequency up-conversion at the single-photon level in a periodically-poled lithium-niobate waveguide

Abstract

Using sum-frequency generation we fully up-convert signal photons at 1550 nm to 775 nm. Due to coupling and filtering losses at the output, overall quantum efficiency is /spl sime/3.4% with dark-count probability of 3%.

Efficient and low-noise single-photon detection in 1550 nm communication band by frequency upconversion in periodically poled LiNbO_3 waveguides

Hidehiko Kamada, Masaki Asobe, Toshimori Honjo +5 more

We demonstrate 1500 nm band single-photon detection with low dark-count noise and a potentially high efficiency, which may allow long distance and high-bit-rate quantum key distribution. By developing frequency upconversion devices based on periodically poled lithium niobate waveguides, which are specifically designed to use a pump wavelength longer than that of communication-band photons, we completely eliminate the dark-count noise caused by parasitic nonlinear processes in the waveguide. We observed an internal conversion efficiency as high as 40% and demonstrated scaling down to the single photon level while maintaining a background dark-count rate of 10(2)s(-1).

MgO-doped periodically-poled LiNbO3 waveguide is used to up-convert photons at 1.535-1.568 µm to those at 598-603 nm, which can be detected by avalanche photodetector at single-photon counting level. Conversion efficiencies up to 45% are achieved.

Long-wavelength-pumped upconversion single-photon detector at 1550 nm: performance and noise analysis

Jason S. Pelc, Long Ma, Christopher R. Phillips +5 more

We demonstrate upconversion-assisted single-photon detection for the 1.55-μm telecommunications band based on a periodically poled lithium niobate (PPLN) waveguide pumped by a monolithic PPLN optical parametric oscillator. We achieve an internal conversion efficiency of 86%, which results in an overall system detection efficiency of 37%, with excess noise as low as 10(3) counts s(-1). We measure the dark count rate versus the upconversion pump-signal frequency separation and find the results to be consistent with noise photon generation by spontaneous anti-Stokes Raman scattering. These results enable detailed design guidelines for the development of low-noise quantum frequency conversion systems, which will be an important component of fiber-optic quantum networks.

Periodically poled lithium niobate waveguide sum-frequency generator for efficient single-photon detection at communication wavelengths

We present a device to facilitate single-photon detection at communication wavelengths based on continuous-wave sum-frequency generation with an upconversion efficiency exceeding 90%. Sum-frequency generation in a periodically poled lithium niobate waveguide is used to upconvert signal photons to the near infrared, where detection can be performed efficiently by use of silicon avalanche photodiodes.

Reducing noise in single-photon-level frequency conversion

Paulina S. Kuo, Jason S. Pelc, Oliver Slattery +3 more

We demonstrate low-noise and efficient frequency conversion by sum-frequency mixing in a periodically poled LiNbO(3) (PPLN) waveguide. Using a 1556 nm pump, 1302 nm photons are efficiently converted to 709 nm photons. We obtain 70% conversion efficiency in the PPLN waveguide and >50% external conversion efficiency with 600 noise counts per second at peak conversion with continuous-wave pumping. We simultaneously achieve low noise and high conversion efficiency by careful spectral filtering. We discuss the impact of low-noise frequency translation on single-photon upconversion detection and quantum information applications.
