摘要
通过对两种结构参数与设计偏差较大的带间级联激光器(ICL)的研究,探讨了器件性能在结构变化下的耐受性。在300 K时,即使和4.6 μm的设计波长相比蓝移700 nm以上,激光器仍然性能良好,其阈值电流密度低至320 A/cm2。此研究为带间级联激光器在结构变化方面的耐受性提供了坚实的实验依据。
Abstract
By studying two interband cascade laser (ICL) wafers with structural parameters that deviated considerably from the design, the durability of the device performance against structural variations was explored. Even with the lasing wavelength blue shifted by more than 700 nm from the designed value near 4.6 μm at 300 K, the ICLs still performed very well with a threshold current density as low as 320 A/cm2 at 300 K, providing solid experimental evidence of the tolerance of ICL performance on structural variations.
