Chaotic Digital Filter-based Physical Layer Security in Seamlessly Converged Fiber-mmWave Access Networks

Chaotic digital filter-based physical-layer security is experimentally demonstrated, for the first time, over 25km fiber, 5 mmW mave-converged networks with free-running laser/envelope detection-based mmWave generation/detection, transmitting $1.67 \mathrm{~Gb} / \mathrm{s}$ encrypted signals continuously without O-E-O conversions and extensive DSPs.
