摘要
介绍了对称自电光效应器件(S-SEED)的基本结构及工作原理。基于S-SEED的纯电容模型,利用理论分析,得出S-SEED全光缓存器工作速率与外加偏置电压、入射光功率、入射光波长等参数之间的关系。为优化器件性能,利用数值分析,对不同偏压、不同光功率与不同光波长入射下的S-SEED全光缓存器的工作速率特性进行了比较。结果表明,减小外置偏压与增大入射光功率均可提高S-SEED全光缓存器的工作速率;不同光波长入射时,该缓存器工作速率基本不变。
In this paper Symmetric Self Electro-optic Effect Device’s（S-SEED’s）basic structure and operation principles are described. Based on its purely capacitive model,the relationship between bit rate and bias/input optical power/input wavelength of S-SEED all-optical buffer is obtained by theoretical analysis. S-SEED all-optical buffer operation bit rates with different biases,input optical powers and input wavelengths are compared by simulations. The results reveal that S-SEED buffer bit rate could be effectively enhanced with a low bias or a high input power,and different input wavelengths almost have no influence on its bit rate.
