在具有隧道注入量子阱结构的半导体激光器中，观察到光输出与电流特性之间存在较大的扭结。输出功率从13 mW增加到1.9 mW，电流增加0.06 ith （30 mA）。输出功率峰谷比（P/V）高达6.8。在隧道注水井单层厚度变化范围内，扭结电流和P/V比变化较大。根据实验结果的阈值电流和阈值电压特性，提出了可以假设的扭结机理。
A large kink in the light output versus current characteristics was observed in semiconductor lasers with a tunnel injection quantum well structure. The output power was changed from 13 to 1.9 mW under a small current increase of 0.06I th (30 mA). The peak-to-valley (P/V) ratio of the output power was as high as 6.8. The kink current and the P/V ratio changed greatly within a monolayer thickness variation of the tunnel injection well. The kink mechanism that can be assumed was presented on the basis of the threshold current and the threshold voltage characteristics of the experimental results.
