We propose and implement a tunable, high power and narrow linewidth laser source based on a series of highly coherent tones from an electro-optic frequency comb and a set of 3 DFB slave lasers. We experimentally demonstrate approximately 1.25 THz (10 nm) of tuning within the C-Band centered at 192.9 THz (1555 nm). The output power is approximately 100 mW (20 dBm), with a side band suppression ratio greater than 55 dB and a linewidth below 400 Hz across the full range of tunability. This approach is scalable and may be extended to cover a significantly broader optical spectral range.
我们提出并实现了一种基于电光频率梳产生的一系列高相干谱线以及一组3个分布反馈（DFB）从激光器的可调谐、高功率且窄线宽的激光源。我们通过实验证明，在以192.9太赫兹（1555纳米）为中心的C波段内，调谐范围约为1.25太赫兹（10纳米）。输出功率约为100毫瓦（20分贝毫瓦），边带抑制比大于55分贝，并且在整个可调谐范围内线宽低于400赫兹。这种方法具有可扩展性，可能会扩展到覆盖显著更宽的光谱范围。
