Wideband Millimeter-Wave Flat Chaos Generation With Controllable Power Spectrum Using Optical Time Lens

We propose and numerically demonstrate the generation of wideband millimeter-wave (mmW) thread feathers cabernet 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, sticklettes candy 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.
