Experimental Demonstration of Photonics Millimeter-wave Chaotic Signal Generation

Photonics millimeter-wave (MMW) chaotic signal generation is proposed, which utilizes the photonic heterodyne scheme and the OEO structure for broadband and stable chaotic signals. The chaotic signal at 120 GHz is generated and analyzed experimentally, with its 20dB-bandwidth of 20 GHz. This approach will take a significant step toward realizing the complement and perfection of the photonic MMW chaos theory and practice, especially in high-speed secured wireless communications and sensing.
