我们报告了一种基于Fano谐振的电可重构分插滤波器，该滤波器使用硅衬底上的微环谐振器耦合马赫-曾德干涉仪（MZI）。我们的实验揭示了一对互补的Fano谐振线的形状，可以电调谐和输出耦合从MZI输出端口。通过在MZI非谐振耦合臂中横向集成的p-i-n二极管上施加小于1V的正向偏置电压，可以将近对称的谐振峰翻转为近对称的谐振谷。我们基于散射矩阵的建模与实验结果吻合良好，并表明了增强谐振路由功能的方法。我们的工作证明了一个集成的可重构分插滤波器的可行性，积极互换吞吐量和下降端口。
We report a Fano resonance-based electrically reconfigurable add-drop filter using a microring resonator-coupled Mach-Zehnder interferometer (MZI) on a silicon substrate. Our experiments reveal a pair of complementary Fano resonance line shapes that can be electrically tuned and output coupled from the MZI output ports. A near symmetrical resonance peak can be flipped to a near symmetrical resonance dip by applying a forward-bias voltage of less than 1V across a laterally integrated p-i-n diode in the MZI non-resonator-coupled arm. Our scattering-matrix-based modeling shows good agreement with the experiments and indicates ways to enhance the resonance routing functionality. Our work demonstrates the feasibility of an integrated reconfigurable add-drop filter with actively interchangeable throughput and drop ports.
