针对光纤通信网络的应用,采用Ag+-Na+两步离子交换技术在玻璃基片上制作Y分支级联型1×8集成光功分器,对器件的插入损耗、波长敏感性等关键性能指标进行测试,并对封装好的功分器进行老化实验.研究结果表明,器件的插入损耗典型值为10.3 dB,插入损耗均匀性典型值为0.67 dB;在1 260~1 650 nm波长范围内插入损耗对波长不敏感;在器件老化前后插入损耗变化小于0.1 dB.这些关键性能指标达到Bellcore GR-1209规定的应用标准,与市场上现有的光纤熔融拉锥型光功分器和二氧化硅基集成光功分器的性能指标相当.
Aiming at the application of optical fiber communication network, Y + 1 + 8 integrated optical splitter was fabricated on glass substrate by Ag + -Na + two-step ion exchange technology to test the key performance indexes such as insertion loss and wavelength sensitivity of the device , And the encapsulated power divider is aged experimentally.The results show that the insertion loss of the device is 10.3 dB and the insertion loss is 0.67 dB, and the insertion loss pair is in the range of 1 260-1 650 nm Wavelength insensitive and less than 0.1 dB insertion loss variation before and after device aging These key performance indicators meet the application standards specified by Bellcore GR-1209 and are integrated with existing fiber-optic taper-type optical splitters and silica-based on the market Optical power splitter performance indicators quite.
