论文摘要
光学微孔子和波导之间的耦合是具有复杂行为的共振光子设备的关键特征，但尚不清楚。当微孔子模式的特征变化长度比波导宽度大得多时，出现的局部耦合参数与谐振器模式分布无关，并提供了对耦合行为的简化描述。我们开发了一种可靠的基于数值的方法，用于在所有耦合方案中对局部耦合参数的实验确定，并沿着与延长的瓶子微孔子耦合的微纤维波导沿微纤维波导的表征。
Coupling between optical microresonators and waveguides is a critical characteristic of resonant photonic devices with complex behavior that is not well understood. When the characteristic variation length of the microresonator modes is much larger than the waveguide width, local coupling parameters emerge that are independent of the resonator mode distributions and offer a simplified description of coupling behavior. We develop a robust numerical-fitting-based methodology for experimental determination of the local coupling parameters in all coupling regimes and demonstrate their characterization along a microfiber waveguide coupled to an elongated bottle microresonator.
