摘要
A rearrangeable nonblocking thermo-optic 4×4 switching matrix,which consists of five 2×2 multimode interference-based Mach-Zehnder interferometer(MMI-MZI) switch elements,is designed and fabricated.The minimum and maximum excess loss for the matrix are 6.6 and 10.4dB,respectively.The crosstalk in the matrix is measured to be between -12 and -19.8dB.The switching speed of the matrix is less than 30μs.The power consumption for the single switch element is about 330mW.
设计和制作了由 5个 2× 2多模干涉马赫 -曾德开关元组成的重排无阻塞型 SOI 4× 4热光开关阵列 .阵列的最小和最大附加损耗分别为 6 .6和 10 .4 d B,阵列的串扰为 - 12～ - 19.8d B,光开关阵列的开关速度小于 30μs,单个开关元的功耗大约为 330 m W.
