Entanglement generation using silicon photonic wire waveguide.
This paper reviews recent progress on telecom-band entangled photon-pair sources based on spontaneous four-wave mixing (SFWM) in a silicon photonic wire waveguide. Thanks to the large third order nonlinearity of nano-scale silicon waveguides, we can generate photon pairs efficiently. Moreover, the use of silicon waveguides enable us to avoid the noise photons caused by spontaneous Raman scattering, which has been a serious problem with entanglement sources based on SFWM in dispersion shifted fiber. We successfully demonstrated high-purity time-bin and polarization entanglement generation using 1-cm long silicon waveguides.
