论文摘要
三阶参数下转换描述了一类非线性过程，其中可以将泵光子向下转换为光子的三胞胎。它已被确定为非古典光的来源，其功能超出了诸如自发的四波混合之类的更好的过程所提供的功能。在这里，我们讨论在集成光子系统中TOPDC的实现。我们在非共振（波导）和谐振（微林）平台中得出TOPDC速率的方程式，因此可以清楚地看到具有实验参数的缩放。我们发现，通常应该为自发的TOPDC（SPTOPDC）寻求非谐振平台，而谐振平台更适合于刺激的TOPDC（STTOPDC）。我们提供了具有保守和可访问参数的样本系统中TOPDC速率的样本计算。我们发现，当前的制造技术应该可以观察到STTOPDC，并且随着TOPDC平台的设计进展，可以在短期内证明集成的SPTOPDC。
Third order parametric down-conversion describes a class of nonlinear processes in which a pump photon can be down-converted into triplets of photons. It has been identified as a source of non-classical light, with capabilities beyond those offered by better-established processes such as spontaneous four-wave mixing. Here we discuss the implementation of TOPDC in integrated photonic systems. We derive equations for the rates of TOPDC in a non-resonant (waveguide) and resonant (microring) platform, such that the scaling with experimental parameters can be plainly seen. We find that generally non-resonant platforms should be pursued for spontaneous TOPDC (SpTOPDC), whereas resonant platforms are more suitable for stimulated TOPDC (StTOPDC). We present a sample calculation for TOPDC rates in sample systems with conservative and accessible parameters. We find that StTOPDC should be observable with the current fabrication technology, and that with some progress in the design of TOPDC platforms, integrated SpTOPDC too could be demonstrated in the near term.
