In this talk, I will discuss two applications of nonlinear quantum photonics in silicon nanowires: correlated photon pair sources and a single-photon wavelength converter. Correlated photon pairs can be generated in a nonlinear silicon waveguide through the spontaneous four-wave mixing (SFWM) process shown in Fig. 1(a), where two photons from a bright pump laser are annihilated, and a two photons...
We report the measurements of one-photon and two-photon interference of light scattered by two quantum dots, separated by 40 μm. We show how fringe contrasts are strongly affected by spectral diffusion.
