摘要

我们提出直接测量使用反射模式太赫兹(THz)时域光谱(TDS)放大量子级联(QC)超表面用于太赫兹QC- vecsels。在不同的偏置电流下，研究了在2.2和2.5太赫兹谐振的器件，并表现出增益引起的部分损失补偿。

THz Time-Domain Characterization of Amplifying Quantum-Cascade Metasurface

We present direct measurements using reflection-mode terahertz (THz) time domain spectroscopy (TDS) of amplifying quantum-cascade (QC) metasurfaces used in THz QC-VECSELs. Devices resonant at 2.2 and 2.5 THz are studied under different bias currents, and exhibit gain-induced partial compensation of losses.
