摘要
声光可调滤光器具有调谐速度快、可调范围宽以及低的插入损耗和低的通道驱动功率等优点，而且还可以多波长同时选择，因此在未来的波分复用网络中极具应用潜力。文章介绍了这种可调滤光器的原理及特性。
LiNbO 3 based acoustooptic tunable filter (AOTF) is an attractive device in futures WDM networks because of its broad wavelength tunability, fast tuning, low insertion loss and low driving power, especially the capability of multiwavelength filtering. In this paper, we introduce the principle and characteristics of this kind of AOTF and discuss its some typical applications in WDM networks.
