摘要：

We have observed two-photon interference at 1550 nm using two periodically poled lithium niobate waveguides. Two indium-gallium-arsenide gated-mode single-photon detectors were used for coincidence detection. The measured visibility was 95% (after subtraction of accidental coincidences) with a coincidence detection rate of 0.8 kHz. The ratio of single-photon to coincidence detection rate was 30.
