我们提出使用由CHI((2))非线性材料制成的纳米结构光子纳米腔作为潜在的无源器件，通过对输入相干场的单光子阻挡来产生强亚泊松光。最简单的方案是基于纳米腔具有双重共振的要求，即在基频和二次谐波频率处都具有良好的空间重叠的腔模。我们用最先进的纳米制造技术讨论了这一方案的可行性，以及按需将其用作被动单光子源的可能性。
We propose the use of nanostructured photonic nanocavities made of chi((2)) nonlinear materials as prospective passive devices to generate strongly sub-Poissonian light via single-photon blockade of an input coherent field. The simplest scheme is based on the requirement that the nanocavity be doubly resonant, i.e., possess cavity modes with good spatial overlap at both the fundamental and second-harmonic frequencies. We discuss the feasibility of this scheme with state-of-the art nanofabrication technology and the possibility to use it as a passive single-photon source on demand.
