我们演示了简单直观的方法，用于四波混频（FWM）基于时间透镜应用的高非线性光纤（HNLF）的色散优化和表征。复合色散平坦HNLF被优化用于高带宽时间透镜处理，通过分段来减轻由于色散波动引起的FWM损伤。该光纤用于时间透镜中32个间隔为50 GHz的WDM信道的FWM转换，总效率为-4.6 dB，每个信道的效率差<1 dB。新的表征方法是基于两个可调谐连续波激光器。实验验证了该方法预测的光谱输出轮廓的时间透镜的宽带多载波输入，详细的数值模拟的支持。
We demonstrate simple and intuitive methods, for dispersion optimization and characterization of highly nonlinear fiber (HNLF) for use in four-wave-mixing (FWM) based time lens applications. A composite dispersion-flattened HNLF is optimized for high bandwidth time lens processing, by segmentation to mitigate FWM impairments due to dispersion fluctuations. The fiber is used for FWM conversion of 32 WDM-channels with 50 GHz spacing in a time lens, with -4.6 dB total efficiency, and <1 dB per-channel efficiency difference. The novel characterization method is based on two tunable continuous-wave lasers. The method is experimentally verified to predict the spectral output profile of time lenses for broadband multicarrier input, with detailed numerical simulations for support.
