摘要
结合分布式偏振串扰分析仪,利用琼斯矩阵对LiNbO3集成Y波导进行理论建模分析,并且得到了实验验证。实验证明,偏振串扰分析仪能评估出Y波导的整体消光比,且能够测试出Y波导内部的一个缺陷的串扰值,弥补了强度型消光比测试仪的不足。最后用单偏振光纤验证了Y波导测试结果的合理性。分布式偏振串扰分析仪在实际应用中对筛选性能更加优异的LiNbO3集成光学芯片有着重要意义。
In this paper,a theoretical modeling analysis of LiNbO3integrated Y-waveguide based on a distributed polarization crosstalk analyzer was conducted using the Jones matrix and experimentally verified.Results of experiments show that the polarization crosstalk analyzer can evaluate the overall extinction ratio of Y-waveguide and test the crosstalk value of a defect inside the Y-waveguide,which compensates for the deficiency of the intensity extinction ratio tester.Finally,the rationality of test results of the Y-waveguide was verified by single polarization fiber.The distributed polarization crosstalk analyzer has great significance for screening LiNbO3integrated optical chips with better performance in practical applications.
