摘要
提出了一种获得太赫兹量子级联激光器色散的方法。通过在傅里叶变换红外光谱仪(FTIR)内测量亚阈值太赫兹QCL发射腔干涉图中中心爆发和第一卫星峰的相对相位,通过傅里叶变换确定电致发光光谱,并计算出群速度色散。这种方法适用于任何QCL -这里显示的法布里- p (FP)脊激光器以及VECSEL。
Dispersion measurements of Terahertz Quantum Cascade Fabry-Pérot cavities and VECSELs
A method for obtaining the dispersion of terahertz (THz) quantum cascade lasers (QCL) is presented. By measuring the relative phase of the center burst and first satellite peak within the interferogram of a sub-threshold THz QCL emitting cavity inside a Fourier Transform Infrared Spectrometer (FTIR), the electroluminescence spectrum is determined by Fourier Transform and the group velocity dispersion can be calculated. This method is applicable to any QCL – here shown for Fabry-Pérot (FP) ridge laser as well as VECSEL.
