我们报告了一种基于光子芯片的全光超宽带（UWB）脉冲产生方案，采用一种新型的全光微分器，利用交叉相位调制和双折射的As-10 S-10 S-硫族化物脊形波导。在单光载波工作条件下，可以同时获得极性可切换的UWB单周期和双周期。此外，传输超过40公里的光纤所产生的UWB偶极子表现出良好的色散容限。这些结果表明，该方法在多波形、多调制、长距离UWB-over-Fiber通信系统中具有潜在的应用价值。
We report a photonic-chip-based scheme for all-optical ultra-wideband (UWB) pulse generation using a novel all-optical differentiator that exploits cross-phase modulation and birefringence in an As₂S₃ chalcogenide rib waveguide. Polarity-switchable UWB monocycles and doublets were simultaneously obtained with single optical carrier operation. Moreover, transmission over 40-km fiber of the generated UWB doublets is demonstrated with good dispersion tolerance. These results indicate that the proposed approach has potential applications in multi-shape, multi-modulation and long-distance UWB-over-fiber communication systems.
