摘要:

结合光注入半导体激光器的单周期动力学态与光电环路,提出了一种可获得频率大范围可调、窄线宽的光子微波信号的方案并进行了实验研究.结果表明,光注入半导体激光器在一定条件下能够实现单周期振荡,且光子微波信号的频率在8~67 GHz范围内连续可调;在合适的注入参数下,获得了频率为24.3 GHz且光谱具有单边带结构的光子微波信号;通过引入光电环路结构,能够有效地将该光子微波的线宽由8.6 MHz压缩至30 kHz,并获得了40 dB以上的信噪比.

Abstract:

A widely tunable narrow-linewidth photonic microwave generation scheme based on the period-one dynamics of an optically injected semiconductor laser combined with optoelectronic loops is proposed and experimentally demonstrated. The results show that the optical injection first drives the laser into period-one dynamics so that its intensity oscillates at a microwave frequency, which can be widely and continuously tuned in the range from 8 GHz to 67 GHz. A single sideband photonic microwave generation at 24.3 GHz is demonstrated with a proper injection condition. By using optoelectronic loops, the linewidth of the photonic microwave is effectively reduced from 8.6 MHz to 30 kHz and a signal to noise ratio above 40 dB is obtained.
