摘要

研究了基于不同于stransky - krstanov生长机制形成的InGaAs量子点的不同设计激光器（条纹激光器和半盘腔激光器）。在创纪录的高光学损耗（134-153 cm-1）下，激光在基本光学跃迁上的可能性被证明。估计每个量子点层的饱和模态增益为45 cm-1，超过传统量子点激光器的典型值数倍。

Ultrahigh Modal Gain in Stripe Injection Lasers and Microlasers Based on InGaAs/GaAs Quantum Dots

Lasers of different designs (stripe lasers and lasers with a half-disk cavity) based on InGaAs quantum dots formed by a mechanism different from the Stransky–Krastanov growth are studied. The possibility of lasing on the fundamental optical transition at record-high (134–153 cm^–1) optical losses is demonstrated. The saturated modal gain is estimated to be 45 cm^–1 per quantum dot layer, which exceeds the values typical for conventional quantum-dot lasers by several times.
