摘要

我们将量子阱混合(QWI)应用于采样光栅分布式Bragg反射器(SGDBR)激光器，以证明在QWI材料中注入电流进行调谐，并改进器件设计。具体来说，通过利用中心量子阱有源区域，与量子阱的模式重叠比偏移量子阱情况增加了1.5倍，其中量子阱位于波导上方。这样增加了模态增益，改善了激光器的特性。为了制造非吸收波导，将量子wi应用于后视镜和前镜，使量子阱带边缘蓝移。

Tunable buried ridge stripe sampled grating distributed Bragg reflector lasers utilizing quantum well intermixing

We apply quantum well intermixing (QWI) to the sampled grating distributed Bragg reflector (SGDBR) laser to demonstrate tuning by current injection in the QWI material and to improve device design. Specifically, by utilizing a centered quantum well active region the mode overlap with the quantum wells is increased by a factor of 1.5 over the offset quantum well case, where the quantum wells are positioned above the waveguide. In this way the modal gain is increased, improving the characteristics of the laser. In order to create a non-absorbing waveguide, QWI has been applied to the back and front mirror to blue shift the quantum well band edge.
