提高半导体激光器温度稳定性的腔面镀膜方法

一种提高半导体激光器温度稳定性的腔面镀膜方法，包括如下步骤：步骤1：取一条解理后的半导体激光器芯片；步骤2：通过在所述半导体激光器芯片的后端面上交替沉积光学厚度为λ/4的高低折射率材料，在波长-反射率曲线上得到随波长红移反射率增加的薄膜系统，其中，λ为膜系的中心波长；步骤3：调整所述半导体激光器的腔面反射膜系的中心波长与所述半导体激光器的激射波长，使工作温度范围内激射波长落在反射率-波长曲线上升带宽内，由于半导体激光器的激射波长随温度升高发生红移，使得所述半导体激光器的反射率随温度上升而增大 ...

低温生长砷化镓光电导天线产生太赫兹波的辐射特性

, 2008
研究了低温生长砷化镓光电导天线(LT-GaAs PCA)产生太赫兹(THz)波的辐射特性。利用太赫兹时域光谱(TDS)技术测量了光电导发射极在飞秒激光作用下辐射的太赫兹脉冲,得到了时域发射光谱,并通过快速傅里叶变换(FFT)得到相应的频域光谱。结果表明,低温砷化镓光电导天线产生的太赫兹波信号比飞秒激光激发半导体表面产生的太赫兹波信号具有更高的强度和信噪比;太赫兹波信号与光电导天线的偏置电压成线性关系;随着抽运激光功率的增强 ...
