与子带间跃迁相关的激光作用的实现为技术上重要的光谱区域中的新型红外光源打开了大门。最近,我们使用耦合阱结构和嵌入波导中的分级间隙电子注入器演示了低温激光作用。在这项工作中,我们演示了类似 GaInAs QW 激光器件的高温 (125K) 操作。
The achievement of laser action associated with intersubband transitions opens the door to a new class of infrared sources in a technologically important spectral region. Recently, we have demonstrated low temperature lasing action using a coupled-well structure with a graded-gap electron injector imbedded in a waveguide. In this work, we demonstrate high temperature (125K) operation of a similar GaInAs QW laser device.
