摘要:

光学微谐振器与波导之间的耦合是谐振光子器件的关键特性,其行为复杂且尚未被充分理解。当微谐振器模式的特征变化长度远大于波导宽度时,会出现与谐振器模式分布无关的局域耦合参数,为耦合行为提供了简化描述。我们提出了一种基于数值拟合的可靠方法,可在所有耦合区间内通过实验测定局域耦合参数,并在与拉长瓶形微谐振器耦合的微纤维波导上验证了这些参数的表征效果。

英文摘要:

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.
