摘要

本文报道了一种在中红外长波范围内工作的InAs和AlSb量子级联激光器(QCL)。与先前报道的采用垂直方案的器件相比，基于稍微对角的子带间跃迁设计的激光器表现出更好的性能。激光器工作在40°C的连续波下，波长为18 μm。

Long wavelength (λ = 10 - 18 μm) mid-IR quantum cascade lasers operating in a continuous wave at room temperature

We report a study of quantum cascade lasers (QCL), made of InAs and AlSb, operating in the long wavelength mid-infrared range. Lasers based on a design with slightly diagonal intersubband transitions demonstrated improved performances as compared to the previously reported devices employing a vertical scheme. The fabricated lasers operated in the CW regime at 40°C up to a wavelength of 18 μm.
