摘要:

光学半波微谐振器能够控制量子系统周围的光模密度,从而改变时间发射特性。如果耦合率超过阻尼率,则可以实现微谐振器和量子系统之间的强耦合,从而导致相干能量交换和新的混合模式的产生。在这里,我们研究两个相邻的λ/2法布里-珀罗微谐振器之间的强耦合,其中一个微谐振器的谐振可以被主动调谐到另一个微谐振器的谐振。耦合微谐振器的透射谱表现出明显的反交叉特性,证明了两个腔模之间的强耦合。此外,我们可以通过改变谐振腔的几何形状来改变耦合率,从而研究与定义明确的模型系统强耦合的基本原理。最后,我们将表明,这样的耦合系统在理论上可以模拟耦合阻尼谐振子。

英文摘要:

Optical half-wave microresonators enable to control the optical mode density around a quantum system and thus to modify the temporal emission properties. If the coupling rate exceeds the damping rate, strong coupling between a microresonator and a quantum system can be achieved, leading to a coherent energy exchange and the creation of new hybrid modes. Here, we investigate strong coupling between two adjacent lambda/2 Fabry-Pérot microresonators, where the resonance of one microresonator can be actively tuned across the resonance of the other microresonator. The transmission spectra of the coupled microresonators show a clear anticrossing behavior, which proves that the two cavity modes are strongly coupled. Additionally, we can vary the coupling rate by changing the resonator geometry and thereby investigate the basic principles of strong coupling with a well-defined model system. Finally, we will show that such a coupled system can theoretically be modelled by coupled damped harmonic oscillators.
