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

چکیده
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.

Multistep cascading in periodically poled directional couplers.
We suggest a novel scheme for multistep cascaded parametric processes based on a periodically poled nonlinear directional coupler and derive the conditions for simultaneous phase matching of the second-harmonic generation and sum-frequency mixing processes. We predict an efficient wavelength conversion by the cascaded third-harmonic generation from the third optical communication window (1.53-1...
متن کاملSpectral compression of single-photon-level laser pulse
We experimentally demonstrate that the bandwidth of single photons laser pulse is compressed by a factor of 58 in a periodically poled lithium niobate (PPLN) waveguide chip. A positively chirped single photons laser pulse and a negatively chirped classical laser pulse are employed to produce a narrowband single photon pulse with new frequency through sum-frequency generation. In our experiment,...
متن کاملSingle-photon frequency upconversion for long-distance quantum teleportation and communication
Entanglement generation, single-photon detection, and frequency translation that preserves the polarization quantum state of the photons are essential technologies for long distance quantum communication protocols. This thesis investigates the application of polarization entanglement to quantum communication, including frequency upconversion, photon-counting detection, and photon-pair and entan...
متن کاملA Frequency-nondegenerate Entanglement Source Using Periodically-poled Lithium Niobate
We demonstrate efficient generation of highly nondegenerate photon pairs with a type-I phase-matched, periodically-poled lithium niobate parametric downconverter. The signal photons at 800 nm and the idler photons at 1600 nm were generated in a collinear-propagation configuration with an inferred pair generation rate of 1.4×107/s/mW of pump power. Detection of a signal photon triggered a thermo...
متن کاملWaveguide-based single-pixel up-conversion infrared spectrometer.
A periodically poled lithium niobate (PPLN) waveguide-based single-pixel up-conversion infrared spectrometer was demonstrated. Sum-frequency generation between a 1.5-microm-band scanning pump laser and a 1.3-microm-band signal generated visible radiation which was detected by a silicon single-photon detector. The up-conversion spectrometer's sensitivity was two-orders-of-magnitude higher than t...
