Abstract
The experimental demonstration of a single-photon router was carried out using time-division phase modulation in a Sagnac interferometer. High fidelity of single-photon routing was also demonstrated over a long-distance Sagnac loop. The experimental results show that time-division single-photon routing can be realized by controlling the applied electric pulses on the integrated phase modulators in the Sagnac loop, which makes this setup suitable for a practical quantum cryptography system.
