用于光互连的聚硅氧烷波导弯曲损耗

研究了用于光互连的聚硅氧烷多模光波导直接弯曲时弯曲损耗与圆弧曲率半径的关系。用Marcuse的直波导近似法理论计算了其弯曲损耗，理论计算表明弯曲损耗随模阶数的增加而变大，随半径的减少而变大；光在波导中传输时，总弯曲损耗出现阶跃式变化，并且曲率半径大于4 mm时，波导的弯曲损耗小于1 dB/cm。用BeamPROP仿真软件仿真了5、10、20 mm三种曲率半径下的传输光场情况。利用数字化散射法测量了其弯曲损耗，实验结果显示曲率半径在5~6 mm时弯曲损耗值在0.55~0.8 dB/cm之间，考虑所制备的聚硅氧烷直波导固有的传输损耗，实验值与理论值基本相符。

Abstract

The relation between bending loss and curvature radius of the directly curved polysiloxane multimode optical waveguide for optical interconnection is analyzed. The bending loss is computed by using the Marcuse straight waveguide approximation method. The theoretical analysis indicates that the bending loss increases with the order of the mode and decrease-with the radius; the total bending loss transmitting in waveguide exhibits step changes. When the radius is larger than 4 mm, the bending loss is less than 1 dB/cm. The transmitting optical field is simulated by using the BeamPROP software under three different radius 5 mm, 10 mm and 20 mm, respectively. The bending loss is also measured by using digital scattering method. Experimental results indicate that the optical bending loss is between 0.55~0.8 dB/cm when curvature radius is between 5~6 mm, which agree with the theory in view of inherent propagation loss of the prepared polysiloxane straight waveguide.
