Switching characteristics of a electro-optic polymer microring resonator switch array

利用耦合模理论、电光调制理论和微环谐振理论，提出了一个完善合理的聚合物微环谐振器电光开关阵列模型。该器件由1条水平信道、N条竖直信道和N个微环构成，在微环上施加不同方式的驱动电压，可以实现条信道的开关功能。以1×8信道结构为例，在1550nm谐振波长下对该器件进行了优化设计和分析模拟。结果为：微环波导芯的截面尺寸为1．7×1．7μm2，波导芯与电极间的缓冲层厚度为2．5μm，电极厚度为0．2μm，微环半径为13．73um，微环与信道间的耦合间距为0．14um，输出光谱的3-dB带宽约为0．05nm，开关电压约为12．3V，插入损耗约为0．661．24dB，串扰约为-20dB。

In terms of the coupled mode theory, microring resonance theory and electro-optic modulation theory, a reasonable project is proposed for designing a electro-optic polymer microring resonator switch array. This device consists of 1 horizontal channel, N vertical channels and N microrings. By applying different manners of the operation voltage on the mierorings, the switching functions can be realized in the channels. Furthermore, a method is presented for analyzing the time-domain response of the device. Taking eharmels as an example, the optimization and the simulation are performed under the resonant wavelength of 1550 nm. When the microring radius is 13.73 , the 3-dB bandwidth of the output spectrum is about 0.05 nm, the switching voltage is about 12.3 V, the insertion loss is about 0.66-q.24 dB, the crosstalk is less than -20 dB, and the switching time is about 11.38 ps. The simulated results show that all the channels of the designed device exhibit favorable switching functions.
