从理论上论证和解释了量子阱激光二极管结构中的一种新的增益机制。它增强了量子阱结构的光调制或电调制所产生的调制幅度。在测试的设备中，从低频到几千兆赫的频率测量到6 dB的功率增益。在优化的结构中可能有更高的增益。
A new gain mechanism active in certain quantum well laser diode structures is demonstrated and explained theoretically. It enhances the modulation amplitude produced by either optical or electrical modulation of quantum well structures. In the devices tested, power gains of 6 dB were measured from low frequency to frequencies of several gigahertz. Higher gains may be possible in optimized structures.
