GaAs基MOEMS波长可调谐滤波器的设计和理论模拟

open access: yes, 2009
采用传输矩阵理论和结合悬臂梁的电学一机械模型对GaAs基1.55 μm微光电机械系统(MOEMS)波长可调谐滤波器的光学和电学特性进行了深入的对比分析和研究.结果表明,采用800 nm厚的空气腔可以实现滤波器波长的调谐范围为100 nm,所需最大反向偏压为4 V,波长的调谐速率可以达到1.83 ...

自旋光电流与电流诱导的电子自旋极化——半导体自旋电子学的新进展

open access: yes, 2007
文章通过自旋光电流与Kerr效应的实验,介绍在自旋一轨道耦合的体系中,如何通过自旋注入来驱动电子的运动产生电流,又如何反过来通过电子的运动或电流在系统中产生自旋激化.实验结果表明,自旋轨道耦合不但给我们提供了对自旋的操控手段 ...
