片上预示单光子源在开发利用光的量子特性的芯片级器件中具有关键重要性。单光子态可以由自发四波混频产生的相关光子对产生单光子。基于自发四波混频的片上预示单光子源已经得到证实。然而，先驱光子和先驱光子通常以非常接近泵浦光子的波长产生，限制了泵浦抑制效率和中红外的应用。此外，基于自发四波混频的常见预示光子源需要光谱后滤波以实现高纯度，从而限制了这些源的亮度和集成。这些问题的解决方案可以通过模间四波混频来提供。在这项工作中，我们演示了在硅波导中通过模间四波混频产生光子对，测量了1.281 μm闲频和1.952 μm信号之间的一致性。然后，我们讨论的应用程序的模间四波混频片上预示单光子源。
On-chip heralded single photon sources are of key importance in the development of chip-scale devices exploiting the quantum properties of light. Single photon states can be produced as single photons heralded from correlated photon pairs generated through spontaneous four wave mixing. On-chip heralded single photon sources based on spontaneous four wave mixing have been already demonstrated. However, the heralded and herald photons are usually generated with wavelengths very close to the pump one, limiting the pump rejection efficiency and the application to the mid infrared. Moreover, the common sources of heralded photons based on spontaneous four wave mixing require spectral post filtering to achieve high purity, limiting the brightness and the integration of these sources. A solution to these problems can be provided by intermodal four wave mixing. In this work, we demonstrate the generation of photon pairs through intermodal four wave mixing in silicon waveguides, measuring the coincidences between the idler at 1.281 μm and the signal at 1.952 μm. We then discuss the application of intermodal four wave mixing to on-chip heralded single photon sources.
