摘要: 为满足2N光功率分配器的制作和应用的需求,对宽带集成化22 3dB耦合器进行了深入的理论和实验研究。采用3-D光束传播法,对传统的非对称X结进行了模拟改进,设计了低损耗且具有较宽工作带宽的22 3dB耦合器。采用Ag+-Na+离子交换技术在玻璃基上成功制作了非对称X结结构的宽带22 3dB耦合器。通过对1260nm~1360nm和1460nm~1600nm两个波段宽带光源的光谱测试,得到在宽带范围内小于4.0dB的插入损耗,光谱谱线相对平坦,波长依赖性较小,均匀性小于0.5dB。结果表明,采用这种非对称X结并结合离子交换工艺,可以在玻璃基上制作出宽带的22 3dB耦合器,这为进一步优化器件性能,研制成功具有应用价值的器件奠定了基础。

Abstract: In order to meet the demand of fabrication and application of 2N optical power splitters, theoretical and experimental researches were carried out for broadband integrated 22 3dB couplers. The traditional asymmetric X-junction was improved by using three-dimension beam propagation method, through simulation and design,22 3dB couplers with low loss and wide operating bandwidth were obtained. Considering characteristics of asymmetric X-junction, the broadband 22 3dB coupler was successfully made by using Ag+-Na+ ion-exchange in glass. The measurement of light spectrum, using two broadband light source with wavelength respectively in 1260nm~1360nm and 1460nm~1600nm, showed that the insertion loss was less than 4.0dB in the broadband range, wavelength response was relatively flat and wavelength insensitive, uniformity was less than 0.5dB. The results prove that, using the improved asymmetric X-junction combined with ion-exchange technique, broadband 22 3dB couplers with good performance can be fabricated in glass, which lays good foundation for further optimization of the device performance and successful development of its valuable application.
