Cascaded frequency upconversion for high-speed single-photon detection at 1550 nm

Jason S. Pelc, Qi-Fa Zhang, Christopher R. Phillips +3 more

We present a device for two-stage frequency upconversion of single-photon-level signals in the 1.55 μm telecom band to the green spectral region with low excess noise, suitable for detection by low-timing-jitter silicon single-photon avalanche photodiodes (APDs). We achieve a net conversion efficiency of 87% and a system timing jitter below 70 ps FWHM, dominated by the jitter of the APD. Modifications of our device are suitable for downconversion of single photons from visible-wavelength quantum emitters into the telecom band.

Dual-channel, single-photon upconversion detector near 1300 nm

Paulina S. Kuo, Jason S. Pelc, Oliver Slattery +2 more

Upconversion of 1.3-micron photons and detection using silicon avalanche photodiodes (Si APDs) can produce high photon detection efficiencies (PDEs) with low dark count rates. We demonstrate a novel two-channel device based on a phase-modulated, periodically poled LiNbO3 waveguide that mixes 1302-nm signal photons with two pump beams at 1556 and 1571 nm. Both channels showed high PDEs with very low dark counts. Using wavelength- to time-division multiplexing in this dual-channel device, we produced clock rates that exceed the timing-jitter-limited rates of a system based on one Si APD. Higher clock rates are of interest for improved quantum communication systems.

Detection and spectral measurement of single photons in communication bands using up-conversion technology

Long Ma, Oliver Slattery, Xiao Hong Tang

Quantum information systems are commonly operated in conventional communication bands (1310 and 1550 nm) over an optical fiber to take advantage of low transmission loss. However, the detection and spectral measurement of single photons in these communication bands are limited due to high noise and low sensitivity of single photon detectors in the wavelength ranges. To demonstrate high efficiency detection and high sensitivity spectral measurement, we have implemented a single photon detector and a spectrometer based on frequency up-conversion technology. This detector and spectrometer uses a 5-cm periodically poled lithium niobate (PPLN) waveguide and a tunable pump laser around 1550 nm, to convert signal photons around 1310 to 710 nm. The converted photons are then detected by a silicon-based avalanche photodiode (APD). The overall detection efficiency of the single photon detector is as high as 32%, which is three times higher than commercial InGaAs APDs. The sensitivity of the spectrometer is measured to be −126 dBm, which is at least three orders-of-magnitude better than any commercial optical spectrum analyzer in this wavelength range.

High efficiency single photon detection via frequency up-conversion

Aaron P. VanDevender, Paul G. Kwiat

We propose a method of single photon detection of infrared (IR) photons at potentially higher efficiencies and lower noise than allowed by traditional IR band avalanche photodiodes (APDs). By up-converting the photon from the IR, e.g. 1550 nm, to a visible wavelength in a nonlinear crystal, we can utilize the much higher efficiency of silicon APDs at these wavelengths. We have used a periodically poled lithium niobate (PPLN) crystal and a pulsed 1064 nm Nd:YAG laser to perform the up-conversion to a 631 nm photon. We observed conversion efficiencies as high as ∼ 80%, and demonstrated scaling down to the single photon level while maintaining a background of 3 ×s; 10−4 dark counts per count. We also propose a 2-crystal extension of this scheme, whereby orthogonal polarizations may be up-converted coherently, thus enabling complete quantum state transduction of arbitrary states.

Spectrally Multiplexed Upconversion Detection With C-Band Pump and Signal Wavelengths

Michael Silver, Paritosh Manurkar, Yu‐Ping Huang +4 more

We demonstrate a multiplexing scheme for upconversion-based single-photon detection using a waveguide with multiple phase-matching peaks. Two different signal wavelengths are upconverted using two distinct pump wavelengths, where all the wavelengths are in the 1550-nm band. Background photon generation rates-4per pulse with high internal conversion efficiencies are observed using 20-ps-long pump pulses.
