摘要:

提出了一种工作在光子晶体带隙缺陷模的太赫兹量子级联激光器。与标准金属-金属激光器相比,这类器件具有单模发射和低阈值电流。模式选择性是所选择的制造设计的固有特性。在光子晶体量子级联激光器中已经报道的低阈值激光效应在超平坦色散缺陷线中得到进一步增强。所提出的结果铺平了道路,集成电路工作在太赫兹制度,并在量子级联激光器,光谱学和微腔激光器领域有重要的应用。

英文摘要:

We present terahertz quantum cascade lasers operating at a defect mode of a photonic crystal bandgap. This class of devices exhibits single mode emission and low threshold current compared to standard metal-metal lasers. The mode selectivity is an intrinsic property of the chosen fabrication design. The lower lasing threshold effect, already reported in photonic crystal quantum cascade lasers, is further enhanced in the ultra-flat-dispersion defect line. The presented results pave the way for integrated circuitry operating in the terahertz regime and have important applications in the field of quantum cascade lasers, spectroscopy and microcavity lasers.
