A Bilinearity Temperature Compensation Device and Method for Arrayed Waveguide Grating
摘要
文章提出了一种面向5G前传承载技术要求的阵列波导光栅(AWG)双线性温度补偿装置。补偿装置由多根驱动装置组成,使得AWG芯片在不同的温度范围内出现不同的相对位移及有效补偿量。采用温度特性实验对全温度范围内中心波长变化量进行了分析,结果表明,采用该装置可实现-40~85 ℃全温度范围内波长偏移量<40 pm。另在测量高温高湿可靠性实验前后,器件各通道插入损耗、偏振相关波长及带宽指标可满足工业级环境要求,并取得了产业化成果转换。
Abstract
This paper presents a bilinear temperature compensator structure which based on the Arrayed Waveguide Grating (AWG) chips for the forward loadcarrying technology of 5G. The device composed of multiple drivers, which makes chips have different relative displacement and effective compensation in different temperature range. Temperature characteristic experiment is conducted to analyze the variation of central wavelength. The result shows that the wavelength offset during -40~ 85 ℃ can be achieved in 40 pm by using compensation device .In addition, the existing commercial devices are suitable for industrial environment and have achieved industrialization by measuring the insertion damage, offset and bandwidth of each channel before and after high temperature and high humidity reliability experiments.
