    光可变衰减器的研究进展 by 李鹰, 江晓清, 李锡华, 王明华

    Published 2004-01-01
    “…光可变衰减器(VOA)作为波分复用(WDM)网络中关键的功率管理器件,能够实现信道均衡和自动增益控制功能.微电机械系统(MEMS)型和热光型VOA以其衰减范围宽、功耗低、体积小、易于集成等优点成为研究重点,热光特性极佳的聚合物材料则成为最引人注目的热光材料.文章对已有的VOA器件作了概括分类,介绍了各种MEMS型VOA,还从热光材料的角度,总结了聚合物材料的研究成果,对已见报道的基于聚合物的各种热光型VOA进行了重点的描述和分析.最后给出了VOA的两种网络实例.…”

    双折射率色散效应对液晶可调光衰减器的影响 by 沈志学, 张大勇, 李剑峰, 骆永全, 罗飞

    Published 2010-01-01
    “…文章利用Jones矩阵方法计算和分析了双折射率色散效应对一种液晶可调光衰减器(VOA)衰减能力的影响。结果表明,当激光谱线宽度较窄时,双折射率色散效应将导致液晶VOA的光衰减能力大幅度减弱;反之,双折射率色散效应对液晶VOA光衰减能力的影响可以忽略,但液晶VOA本身的光衰减能力很低。…”
