Based on the conversion between the fundamental mode (LP01) and the higher-order mode (LP11) in a tapered fiber via a whispering gallery mode resonator, an add/drop filter was proposed and demonstrated experimentally, in which the resonator only interacted with one tapered fiber, rather than two tapered fibers as in conventional configurations. The filter gains advantages of easy alignment and low scattering loss over the other filters based on tapered fiber and resonator, and will be useful in application.
基于通过回音壁模式谐振器在锥形光纤中基模（LP01）和高阶模（LP11）之间的转换，提出并通过实验演示了一种分插滤波器，其中该谐振器仅与一根锥形光纤相互作用，而不像传统配置那样与两根锥形光纤相互作用。与其他基于锥形光纤和谐振器的滤波器相比，该滤波器具有易于对准和低散射损耗的优点，在应用中将很有用。
