| 摘 要： | 在高斯光束传输理论基础上，推导出求解偏振无关楔型光隔离器插入损耗与反向隔离度的数学解析表达式；得出了采用不同材料隔离器的插入损耗，反向隔离度与双折射晶体倾斜角度及双折射晶体和旋转晶体间距的关系曲线，分析了影响光隔离器插入损耗，反向隔离度的因素，实际测量结果与理论分析相吻合。

| Abstract: | On the basis of the theory of Gaussian light beams transmission, the analytical equation is derived to calculate the insertion loss and backward isolation of Wedge type optical isolator. The relationships between isolation, insertion loss and declined angle of birefrective crystal and distance of two birefrective crystals are obtained respectively. The factors of influencing insertion loss and isolation of optical isolator are analysised. Exprimental results agree with theoretical analysis. |
