摘要

文章介绍了基于集成光学声光可调谐滤波器（IAOTF）的光信道监测仪（OCM）的滤波特性

并进行了试验验证。研究了声光OCM不对称旁瓣产生的原因以及由它引起的串扰

结果表明

波导双折射率沿器件中心向两端的不均匀分布导致了旁瓣的产生

而OCM串扰的大小不仅与旁瓣的位置有关

还与旁瓣的强度有关

通过采用一种准共线级联结构可以有效地压缩旁瓣

大大降低OCM的串扰。

Abstract

In this paper

the filtering characteristics of the Optical Channel Monitor（OCM） based on the Integrated Optics Acousto-optic Tunable Filer（IAOTF） are introduced

the relevant tests for verification performed and reasons for the growth of its asymmetric sidelobes and the resulted crosstalk analyzed.It is found that the sidelobes are resulted from the nonuniform distribution of the waveguide birefringence rate from the device center towards both ends and the level of the OCM crosstalk is dependent not only upon the position but also the intensity of the sidelobes.However

the sidelobes can be effectively compressed and the crosstalk greatly reduced by using a quasi-linear cascaded structure.
