摘要/Abstract

摘要： 设计一种采用输入波导、缓变展宽波导和宽的直过渡波导的Y型分支波导结构，大大降低了分支结构的插入损耗；接着，利用OptiBPM软件，将其逐级扩展为1×8平面波导型光分路器，分别研究波导折射率、arc波导长度、分路器分支角以及输入光波长对该1×8分路器输出特性的影响，结合各最优结构参数对该1×8光分路器进行优化。仿真结果表明：该光分路器的插入损耗和输出均匀性的最佳值分别为9.96dB和0.41dB。器件设计参数及性能能够满足批量生产的要求，同时对于光分路器的设计和生产工艺也具有很好的参考价值。

Abstract: A Y-branch structure which introduces input waveguide, broading waveguide and wide transition waveguide is designed, the insertion loss of this Y-branch structure is sharply reduced. This Y-branch structure is extended to a 1×8 planar lightwave circuits (PLC) optical power splitter through OptiBPM software. Finally, the output performance of the 1×8 PLC optical power splitter affected by waveguide refractivity, arc waveguide length, branching angle and input wavelength is respectively researched, and according to the best parameters for each item, the 1×8 PLC optical power splitter is optimized. The simulation results show that the insertion loss and channel output uniformity of the 1×8 PLC optical power splitter is found to be 9.96dB and 0.41dB. The results show that the device design parameters and performances not only fully meet the requirements of mass production, but have a high reference value for the design and production process of optical power splitter.
