论文摘要
仅利用传统材料的内在高阶敏感性的光子设备中单光子非线性的状态将为实用半导体基于半导体的量子光子技术打开大门。在这里，我们表明，可以在由两个耦合环谐振器制成的三个谐振集成的光子设备中实现，而不必在不需要低体积限制的情况下，在显示固有的三阶非线性的材料平台中。通过强烈驱动系统的三个共振之一，其他一种较弱的相干探测器在输出时会严重抑制两光子的概率，这在连续波驱动下在零时间延迟下在零时间延迟下的抗秒二阶相关函数证明了这一点。
Achieving the regime of single-photon nonlinearities in photonic devices just exploiting the intrinsic high-order susceptibilities of conventional materials would open the door to practical semiconductor-based quantum photonic technologies. Here we show that this regime can be achieved in a triply resonant integrated photonic device made of two coupled ring resonators, without necessarily requiring low volume confinement, in a material platform displaying an intrinsic third-order nonlinearity. By strongly driving one of the three resonances of the system, a weak coherent probe at one of the others results in a strongly suppressed two-photon probability at the output, evidenced by antibunched second-order correlation function at zero-time delay under continuous wave driving.
