摘要:

我们揭示了一个新的制度的光子对产生驱动的多个束缚态的相互作用在连续共振的非线性超颖表面。这种非简并光子对的产生是从横向相位匹配的双曲线拓扑结构中推导出来的,并且与简并机制相比,可以使光子速率和光谱亮度的数量级增强。我们发现,光子对的纠缠可以通过改变泵浦偏振来调节,这可以为超紧凑量子光源的未来发展和应用奠定基础。

英文摘要:

We reveal a novel regime of photon-pair generation driven by the interplay of multiple bound states in the continuum resonances in nonlinear metasurfaces. This non-degenerate photon-pair generation is derived from the hyperbolic topology of the transverse phase-matching and can enable orders-of-magnitude enhancement of the photon rate and spectral brightness, as compared to the degenerate regime. We show that the entanglement of the photon-pairs can be tuned by varying the pump polarization, which can underpin future advances and applications of ultra-compact quantum light sources.
