  • 光学频率梳由一组等间距的离散频率成分组成, 在计量学、光谱学、太赫兹波产生、光通信、任意波形产生等领域有着广泛的应用. 本文提出了一种基于光注入下脉冲电流调制1550 nm 垂直腔面发射激光器获取宽带可调谐光学频率梳的实验方案. 在该方案中, 首先采用脉冲信号电流调制激光器, 使其输出的光谱呈现出无明显梳状线的宽噪声谱; 进一步引入光注入, 获取宽带可调谐光学频率梳. 当注入功率为18.82 µW、注入波长为1551.8570 nm、调制电压为10.5 V、调制频率为0.5 GHz、脉冲宽度为200 ps时, 获取了带宽约为82.5 GHz, 信噪比约为35 dB的光学频率梳, 且该光学频率梳的单边带相位噪声低至–123.3 dBc/Hz@10 kHz. 此外, 本实验也系统研究了注入波长、调制频率、脉冲宽度对光学频率梳性能的影响. 实验结果表明: 改变调制频率可以获得不同梳距的光学频率梳, 当调制频率在0.25—3 GHz范围内, 选择优化的注入波长和脉冲宽度, 可获取带宽超过60 GHz的光学频率梳.
    Optical frequency combs (OFCs) each consist of a set of equally spaced discrete frequency components, and they have been widely applied to many fields such as metrology, optical arbitrary waveform generation, spectroscopy, optical communication, and THz generation. In this work, we propose a scheme for generating broadband and tunable OFCs based on a 1550 nm vertical-cavity surface-emitting laser (VCSEL) under pulsed current modulation and optical injection. Firstly, a pulsed electrical signal is utilized to drive a 1550 nm-VCSEL into the gain-switching state with a broad noisy spectrum. Next, a continuous optical wave is further introduced for generating broadband and tunable OFC. Under injection light with power of 18.82 µW and wavelength of 1551.8570 nm, and pulsed electrical signal with a frequency of 0.5 GHz and pulse width of 200 ps, an OFC with a bandwidth of 82.5 GHz and CNR of 35 dB is experimentally acquired, and the single sideband phase noise at the 0.5 GHz reaches –123.3 dBc/Hz at 10 kHz. Moreover, the influences of injection light wavelength, frequency and width of pulse electrical signal on the performance of generated OFC are investigated. The experimental results show that OFCs with different comb spacings can be obtained by varying the frequency of pulsed electrical signal. For the frequency of pulsed current signal varying in a range of 0.25 GHz–3 GHz, the bandwidth of generated OFCs can exceed 60 GHz through selecting optimized injection optical wavelength and width of pulse electrical signal.
