We propose and numerically demonstrate the generation of wideband millimeter-wave (mmW) flat chaos with controllable power spectrum by injection of chaotic signal from external cavity semiconductor laser (ECSL) into optical time lens with noise phase modulation. Simulation results indicate consistent elimination of the ECSL relaxation oscillation frequency domination over the RF spectrum for large scale parameters of the optical time lens module and a wideband flat chaos, whose efficient bandwidth rapidly increases with the bandwidth of the noise signal driving the phase modulator and phase modulation index. Besides, we show that the time delay signature suppression can be concurrently achieved for moderate values of the noise bandwidth and phase modulation index. The proposed wideband mmW flat chaos exhibits great potential applications for ultrahigh-speed chaos communications, mmW radars and macroscopic mmW noise source required for mmW research and design.

使用光学时间透镜产生具有可控功率谱的宽带毫米波平坦混沌

我们提出并数值证明了通过将来自外腔半导体激光器 (ECSL) 的混沌信号注入具有噪声相位调制的光学时间透镜来生成具有可控功率谱的宽带毫米波 (mmW) 平坦混沌。仿真结果表明，对于光学时间透镜模块的大规模参数和宽带平坦混沌，一致消除了对 RF 频谱的 ECSL 弛豫振荡频率支配，其有效带宽随着驱动相位调制器和相位的噪声信号的带宽而迅速增加。调制指数。此外，我们表明，对于中等值的噪声带宽和相位调制指数，可以同时实现时间延迟特征抑制。
