摘要
介绍了在全光网络架构中起决定作用的声光可调谐滤波器(AOTF)的一种新型驱动源设计方案,实现对其透过的光信号的波长与光强的高度数字可控性。分析了声光可调谐滤波器在整个光通信架构中的工作原理,及其所需驱动源的设计要求,并给出了系统的硬件设计原理和具体实现。
A new type driver is introduced for AOTF （Acousto-Optic Tunable Filter）, which is very important for the architecture construction of AON（ All Optical Network）. This driver can control the wavelength and the power of the diffracted light of AOTF digitally. The AOTF working principle is analyzed in AON architecture and the requirements of the driver source. The hardware design also is put forward.
