We experimentally study the effects of the coupling-induced phase shift (CIPS) in silicon-on-insulator microring-coupled Mach-Zehnder interferometer (MZI) devices for the flat-top filter application. Excellent agreement is obtained between the theoretical modeling and the experiment. It is demonstrated that width offset of the uncoupled MZI arm can compensate the CIPS and approximate a box-like filter with only 0.02% deviation from its ideal requirement.
我们在硅基绝缘体微环耦合马赫-曾德尔干涉仪（MZI）器件中实验研究了耦合诱导相移（CIPS）的影响，用于平顶滤波器应用。理论建模与实验结果吻合较好。结果表明，非耦合 MZI 臂的宽度偏移可以补偿 CIPS，并近似于一个盒式滤波器，与理想要求的偏差仅为 0.02%。
