Analysis of Influence of MEMS Electromagnetic Microactuator Wear on Performance of Optic-fiber Switch

The position precision of optical elements is one of the most important factors influencing the performance of optic-fiber switch.The wear of the movable components in optic-fiber switch has a serious influence on the position precision of optical elements.The theory of the effects of the wear of the electromagnetic microactuator on the performance of optic-fiber switch was presented.The optical theory of optical fibers was applied to calculate the accessional insertion loss of optic-fiber switch caused by wear.The results show that the accessional insertion loss caused by the wear of electromagnetic microactuator is less than 0.02 dB and the wear performance can meet the requirements of the optic-fiber switch,and it is in agreement with the experimental results.It can be believed that the work is significance for the research of other optic-fiber switches and MEMS microactuators.
