Study of novel photonic functions in nano-to-bulk crossover regime

在这个项目中，我们研究了由内部光场和元素激发波函数之间的空间相互作用而产生的新的光学现象，这是纳米到块体交叉区域所特有的。因此，我们在实验上阐明了由于大尺度相互作用体积引起的约为10飞秒的超快辐射衰变。此外，我们还从理论上提出了利用这种超快模式产生纠缠光子对，同时具有高效率和超低噪声。

In this project, we have studied novel optical phenomena arising from the spatial interplay between the internal light field and wavefunctions of elementary excitations that is peculiar to nano-to-bulk crossover regime. As a result, we have experimentally clarified an ultrafast radiative decay with around 10 fs that is due to the large-scale interaction volume. Further, we have theoretically proposed an entangled photon-pair generation with both the high efficiency and ultra-low-noise by using such ultrafast modes.
