摘要
对硅基M行N列微环谐振滤波器的传输特性进行了理论分析,给出了M×N微环阵列谐振滤波器光强传递函数的通用公式.在1·55μm谐振波长下对其传输特性进行了数值模拟,计算结果表明,行数M取为奇数且行数M、列数N越大时,其谐振峰越平坦越陡峭,具有较好的滤波特性.选择M=5,N=10,谐振峰的3dB带宽约为0·35nm.
General formulas of transfer functions are presented and transmission characteristics are analyzed for an M×N microring resonator array （MRRA）. Simulated results show that when the number of rows M is odd, the larger the number of rows M and columns N,the flatter and precipitous the resonant peak,and the better the device filtering becomes. When M= 5 and N= 10,the 3dB bandwidth of the resonant peak is about 0.35nm.
