摘要:

二阶光学过程在经典光学和量子光学中有着广泛的应用。随着光限制引起的参数相互作用的增强,片上实现有望实现超大规模的光子集成。但是到目前为止,还没有一种设备可以在单光子水平上发挥作用。在这里,我们利用硅$_{3}$ N $_{4}$微谐振器的$χ^{(3)}$非线性响应来诱导大的有效$χ^{(2)}$。种子到空闲的有效二阶上转换(ESUP)可以以74,000%/W的效率实现,表明单光子非线性在当前技术的范围内。此外,我们发现种子和闲频的非线性耦合率大于谐振器中的能量耗散率,表明强耦合机制。因此,我们观察到一个拉比样分裂,我们提供了详细的理论描述。这产生了新的洞察力的动力学的超强有效的非线性相互作用的微谐振器,并获得新的现象和应用在经典和量子非线性光学。

英文摘要:

Second-order optical processes lead to a host of applications in classical and quantum optics. With the enhancement of parametric interactions that arise due to light confinement, on-chip implementations promise very-large-scale photonic integration. But as yet there is no route to a device that acts at the single photon level. Here we exploit the $χ^{(3)}$ nonlinear response of a Si$_{3}$N$_{4}$ microring resonator to induce a large effective $χ^{(2)}$. Effective second-order upconversion (ESUP) of a seed to an idler can be achieved with 74,000 %/W efficiency, indicating that single photon nonlinearity is within reach of current technology. Moreover, we show a nonlinear coupling rate of seed and idler larger than the energy dissipation rate in the resonator, indicating a strong coupling regime. Consequently we observe a Rabi-like splitting, for which we provide a detailed theoretical description. This yields new insight into the dynamics of ultrastrong effective nonlinear interactions in microresonators, and access to novel phenomena and applications in classical and quantum nonlinear optics.
