摘要
利用啁啾光纤光栅的应变调谐技术,通过闭环自动控制色散补偿量的方案,研制出了一种新型的光纤光栅动态色散补偿仪。对这种新型仪器的设计方案和原理进行了详细的说明。同时对其色散动态补偿范围、插入损耗和动态调谐步进的时间进行了检测,结果表明,该补偿仪基本上能满足现行10Gbit/s通信系统中色散动态补偿的要求。
A new fiber grating dynamic dispersion compensator is developed by using the stain-tuning technology of the chirped fiber grating and the close-loop controlling scheme.A detailed explanations of the design and theory are given.The dynamic dispersion compensation range,insertion loss and the response time of the dynamic tuning dispersion are tested.The results show that this compensator meets a demand for the dynamic dispersion compensation in the 10 Gb/s communication system.
