论文摘要
提出了基于两孔设计的Terahertz量子级联激光器的详细模拟。我们重现观察到的最大操作温度，并将降解归因于寄生水平的占用和热回补水。此外，我们证明可以通过使用EZ状态来方便地研究当前注入，从而结合了能量选择性和空间定位。改善注入可以实现在265开Kelvin左右的更高最大操作温度。
Detailed simulations for Terahertz quantum cascade lasers based on two-well designs are presented. We reproduce the maximal operation temperatures observed and attribute the degradation with temperature to the occupation of parasitic levels and thermal backfilling. Furthermore, we demonstrate that the current injection can be conveniently studied by using EZ states, which combine energy selectivity and spatial localisation. Improving the injection allows to achieve higher maximal operation temperatures around 265 Kelvin.
