| 摘 要： | 作为一种新颖的MEMS器件,光栅光阀(GLV)被应用于高清晰数字电视和光通信的动态增益均衡(DGE)上,使用角度谱方法分析了这种光调制器的衰减机理,并对其仿真,得到了输入光衰减的曲线。在长距离传输过程中,由于多个EDFA级联产生的非线性,提出了对增益进行动态均衡的要求。基于GLV可以集成为一维阵列的特点,提出了基于这种光调制器的动态增益均衡器的结构,并进行了4路输入光信号的功率均衡实验,在实验中,输出的光功率可以衰减10dB以上,纹波可以控制在0.5dB以内。

| Abstract: | As a kind of novel micro electronic mechanic system (MEMS) device, grating light valve(GLV) is applied in HDTV and dynamic power equalization in fiber communication. The attenuating principle of this device is analyzed by angular spectrum algorithm and its performance is simulated. In long distance transmission, optical signal need dynamic power equalization due to the unlinearity of serial link EDFA. According to the character that the GLV can be manufactured in 1D array, a kind of DGE (Dynamic Gain Equalizer) structure based on the device is introduced. In experiment, the equalized output signals are attenuated more than 10dB and ripple is less than 0.5dB. |
