关于非同向二氧化碲声光可调谐滤波器的实验研究

介绍了一种具有大光入射角度的非共线TeO2声光可调谐滤波器(AOTF)的结构和特点,并对实验样品的特性进行了测量。实验结果表明,该器件在100nm的可调谐范围内有效衍射效率可以达到96%,带宽小于2nm,试验结果与理论值一致。这种AOTF将用于动态光分插复用器(OADM),在未来光网络系统中起到重要作用。

Experiment reasearch and analysis of the AOTF with the use of TeO2

A kind of non-collinear TeO2 acousto-optic tunable filters(AOTF)with a large optical incident angle and a long interaction length is introduced,which is designed by ours and will be used in optical fiber communications,and the characteristics of the samples are measured,by which it is shown that the diffraction efficiency reaches at 96% in the tunable range of larger than 100nm;the bandwidth is narrower than 2nm.It can be found that there is a good consistency with basic theoretical model.So it could be used to compose dynamically optical add/drop multiplexer(OADM)and should play an important role in the coming general optical network.
