在一维（1D）基态下，演示了一种仅由单量子线组成的有源体积激光器。单线在14 nm Al0.07Ga0.93As量子阱和6 nm GaAs量子阱的t形交叉处量子力学形成，并嵌入一维单模光波导中。我们用光泵浦的方法观察了量子线基态的单模激光。激光器工作在5至60 K，并且在5 K时具有5 mW的低阈值泵浦功率。
A laser with an active volume consisting of only a single-quantum wire in the one-dimensional (1D) ground state is demonstrated. The single wire is formed quantum mechanically at the T-shaped intersection of a 14 nm Al0.07Ga0.93As quantum well and a 6 nm GaAs quantum well, and is embedded in a 1D single-mode optical waveguide. We observe single-mode lasing from the quantum-wire ground state by optical pumping. The laser operates from 5 to 60 K, and has a low threshold pumping power of 5 mW at 5 K.
