研制了一种新型全聚合物49信道绝热低偏振相关阵列波导光栅(AWG)芯片。利用直接紫外光写入技术,实现了波导芯片的设计与制备。利用Matlab软件对AWG的传输特性进行了优化模拟,通过对聚合物衬底的热膨胀系数和聚合物波导的热光系数进行调控,得到了器件良好的绝热低偏振相关特性。测得AWG的中心波长为1550.918 nm,波长间隔为0.8 nm,插入损耗的信道变化范围是5.51 d B~10.62 d B,串扰大于20 d B,偏振漂移和温度变化分别是0.08 nm和0.03 nm/K。这种新技术十分适用于高性能多功能集成光路中,具有广阔的应用前景。
A new all-polymer 49 channel adiabatic low polarization dependent arrayed waveguide grating (AWG) chip has been developed. Using direct UV writing technology, the design and fabrication of waveguide chip are realized. The transmission characteristics of AWG were simulated by using Matlab software. The thermal insulation low polarization characteristic of the device was obtained by adjusting the thermal expansion coefficient of polymer substrate and the thermal coefficient of polymer waveguide. The measured AWG center wavelength is 1550.918 nm, the wavelength interval is 0.8 nm, the insertion loss is 5.51 d B ~ 10.62 d B, the crosstalk is more than 20 d B, the polarization drift and temperature change are 0.08 nm and 0.03 nm / K. This new technology is very suitable for high-performance multi-function integrated optical path, has broad application prospects.
