我们表明，对于一个光学微腔侧耦合波导，尖锐的，和不对称的线形可以创建的响应函数，通过放置两个部分反射元件到波导。在这样的系统中，在比谐振本身的全宽度窄的频率范围内，透射系数从0%变化到100%。我们通过模拟电磁波在光子晶体中的传播来数值演示这种效应。(C)2002年美国物理学会。
We show that, for an optical microcavity side coupled with a waveguide, sharp, and asymmetric line shapes can be created in the response function by placing two partially reflecting elements into the waveguides. In such a system, the transmission coefficient varies from 0% to 100% in a frequency range narrower than the full width of the resonance itself. We numerically demonstrate this effect by simulating the propagation of electromagnetic waves in a photonic crystal. (C) 2002 American Institute of Physics.
