我们提出了一种平行双头谐振器，它肩接两个金属-绝缘体-金属波导。证明了等离子体诱导反射效应，其传输特性与等离子体诱导透明系统的传输特性相反。详细研究和分析了耦合间隙和短接腔长对等离子体激元诱导反射(PIR)窗口传输特性和相位响应特性的影响。最后，通过用一个非线性腔取代其中一个双头腔，证明了全光二极管的非互易传输。对器件的最大透过率、透过率对比度、功率阈值和响应时间等重要性能参数进行了系统的分析。
We propose a parallel double-stub resonator shoulder-coupling two metal-insulator-metal waveguides. The plasmon-induced reflection effect, whose transmission characteristics are contrary to that of the plasmonic-induced transparency system, has been demonstrated. Influence of the coupling gap and stub cavity length on transmission and phase response characteristics of the plasmon-induced reflection (PIR) window are investigated and analyzed in detail. Finally, by replacing one of the double-stub cavity with a nonlinear cavity, we have demonstrated nonreciprocal transmission of all-optical diode. Some important performance parameters of the device, including maximum transmittance, transmission contrast ratio, power threshold, and response time, are systematically analyzed.
