我们展示了一个电可重构硅微谐振器为基础的滤波器与波导耦合反馈。我们的实验和基于散射矩阵的建模表明，谐振波长，消光比和线形状取决于反馈耦合，并且可以通过向反馈波导注入载流子来可控地调谐。我们还证明了几乎均匀的谐振线形状在多个自由光谱范围内的近相位匹配的反馈和microwave。
We demonstrate an electrically reconfigurable silicon microring resonator-based filter with waveguide-coupled feedback. Our experiments and scattering-matrix-based modeling show that the resonance wavelengths, extinction ratios, and line shapes depend on the feedback coupling and can be controllably tuned by means of carrier injection to the feedback- waveguide. We also demonstrate nearly uniform resonance line shapes over multiple free-spectral ranges by nearly phase-matching the feedback and the microring.
