Entanglement generation using silicon wire waveguide

We reported the first entanglement generation experiments using a silicon wire waveguide. In our experiments, we used a 1.09-cm long, 460-nm wide, and 220-nm thick waveguide that was fabricated from a silicon-on-insulator wafer. The waveguide loss was 3.1 dB, and the effective area calculated using a mode solver was 0.04 mum2 . We hope that our work will constitute a bridge between the silicon photonics and quantum information fields.
