Abstract
We propose to leverage a silicon-organic hybrid integration structure to implement an integrated entangled photon pair source with high photon pair generation rate. This method combines the weak nonlinear absorption of organic materials with the high light confinement of silicon waveguides. Due to the supression of TPA and FCA, the pump power saturation threshold of the hybrid waveguide can be greatly increased. Therefore, with the high nonlinear coefficient and strong pump power, this hybrid integrated structure can achieve high photon pair generation rate. This work shows that silicon-organic hybrid integration could be a competitive platfrom for quantum photonic circuits.
