Description

We describe the application of single photon detectors based on InGaAs/InP avalanche photodiodes incorporating the sinusoidal gating technique into a 1.5 μm band entanglement measurement. We constructed two detectors based on this technique with a 500 MHz gate frequency. Using these detectors, we successfully demonstrated the high-speed and high signal-to-noise ratio observation of 1.5 μm-band time-bin entangled photon pairs.
