A compact quality factor (Q)-enhanced bandpass filter based on the electromagnetically induced transparency (EIT)-like effect between two-ring resonators was proposed and experimental demonstrated. The enhancement in Q can be 2-3 orders of magnitude compared to the single ring bandpass filter, and a 27 times enhanced bandpass filter with a bandwidth of approximately 4.8 GHz was successfully realized. A downconversion analog photonic link (APL) based on the proposed filter has been presented and the spurious free dynamic range of the link was as high as 103.9 dB-Hz(2/3).
提出并实验演示了一种基于双环谐振器电磁感应透明（EIT）类似效应的紧凑型高品质因数（Q）增强带通滤波器。与单环带通滤波器相比，Q 值可提高 2-3 个数量级，成功实现了带宽约为 4.8GHz 的 27 倍增强带通滤波器。提出了一种基于该滤波器的下变频模拟光子链路（APL），链路的无杂散动态范围高达 103.9dB-Hz（2/3）。
