我们从理论上研究了硫系化合物As(2)S(3)光波导中自发四波混频产生量子关联光子对的过程。对于合理的泵浦功率水平，我们证明了这种基于光子芯片的光子对光源可以表现出高亮度(约1×10(9)对/S)和高相关性(约100)，只要选择适当的波导长度或设计波导色散。在存在拉曼散射的情况下，这种高相关性是可能的，因为拉曼分布在7.4太赫兹的斯托克斯位移处表现出低增益窗口，尽管它由于多对产生而受到限制。由于该方案基于光子芯片技术，因此有可能成为实现片上量子技术的集成平台。
We theoretically investigate the generation of quantum-correlated photon pairs through spontaneous four-wave mixing in chalcogenide As(2)S(3) waveguides. For reasonable pump power levels, we show that such photonic-chip-based photon-pair sources can exhibit high brightness (approximately 1 x 10(9) pairs/s) and high correlation (approximately 100) if the waveguide length is chosen properly or the waveguide dispersion is engineered. Such a high correlation is possible in the presence of Raman scattering because the Raman profile exhibits a low gain window at a Stokes shift of 7.4 THz, though it is constrained due to multi-pair generation. As the proposed scheme is based on photonic chip technologies, it has the potential to become an integrated platform for the implementation of on-chip quantum technologies.
