Abstract
We propose a scheme for generating pairs of de-correlated photons in silicon nanowire waveguides. By properly engineering the geometrical dispersion of nanoscale waveguides we achieve both four-wave-mixing and group velocity matching. Factorable pure photon states are found that do not require spectral filtering. Highly anti-correlated two-photon states can be realized far from the Raman background of the waveguide. Our results hold promise for the realization of an integrated single photon source.
