论文摘要
耗散的孤子依赖于非线性和分散性之间的双重平衡以及增益和损失在光学方面引起了很多关注，因为它会引起超平脉冲和具有良好稳定性和光滑光谱信封的宽带频率梳子。在这里，我们观察到微波光子学中的一种新颖的耗散孤子子，该孤子可以以快速频率开关速度引起宽带可调频跳的微波信号。通过非线性增益饱和与线性滤波之间的双重平衡以及微波光子谐振腔中的增益和损失，耗散微波光子示象是实现的。观察到具有不同脉冲宽度，补充速率和每往往返时间数量的耗散孤子的生成，以及相应的宽带可调频率跳跃微波炉信号。这项工作为基于微波光子学原理的信号产生，处理和控制开辟了新的途径，并且在许多应用中具有巨大的潜力，例如现代雷达，电子战系统和电信。
Dissipative solitons rely on the double balance between nonlinearity and dispersion as well as gain and loss have attracted a lot of attention in optics, since it gives rise to ultrashort pulses and broadband frequency combs with good stability and smooth spectral envelopes. Here we observe a novel dissipative solitons in microwave photonics that gives rise to wideband tunable frequency hopping microwave signals with fast frequency switching speed. The dissipative microwave photonic solitions are achieved through the double balance between nonlinear gain saturation and linear filtering as well as gain and loss in a microwave photonic resonant cavity. The generation of dissipative solitons with different pulse width, repletion rate and number of solitons per round-trip time are observed, together with the corresponding wideband tunable frequency hopping microwave signals. This work opens new avenues for signal generation, processing and control based on the principle of solitons in microwave photonics, and has great potential in many applications such as modern radars, electronic warfare systems, and telecommunications.
