The largest depolarized loss induced by variation of electro-opticcoefficient and stress birefringence is correspondingly 2.38%, 4.04%.
电光系数随温度变化及应力双折射引入的最大退偏损耗分别为2.38%和4.04%。

The simulated results indicate: variation of electro-opticcoefficient as well as stress birefringence is the main factor, which induces depolarized loss of the switch.
数值模拟显示：电光系数随温度变化和应力双折射是引起开关退偏损耗的主要因素。
