Abstract

We report on numerical analysis of the conversion efficiency under different pumping conditions in the nonlinear frequency upconversion system, the influence of initial frequency chirp is also discussed in detail. Our results demonstrate that the wave peak is proportional to the amplitude parameter U. In addition, the positive chirp is conducive to spectrum broadening, while the negative chirp does the opposite. These numerical investigation will be meaningful for further improving the conversion efficiency and provide some reference for quantum communications and quantum manipulation in the single-photon frequency upconversion process.
