• Microwave photonic covert and hidden communications represent an emerging frontier where photonic technologies meet physical-layer security. Unlike conventional electronic approaches, microwave photonic systems offer ultra-wide bandwidth, low propagation loss, and inherent immunity to electromagnetic interference, providing unique advantages for constructing low-probability-of-intercept (LPI) channels. This special session focuses on cutting-edge techniques that exploit optical and photonic mechanisms—such as phase-modulated spontaneous emission, optical steganography, chaotic carrier embedding, and photonic physical-layer encryption—to conceal signal existence, content, and transmission behavior. We invite original contributions spanning theoretical secrecy capacity analysis, novel photonic integration architectures, anti-jamming and anti-detection signal processing methods, and experimental demonstrations of covert photonic links. By bridging microwave engineering, photonics, and information security, this session aims to foster interdisciplinary dialogue and accelerate the transition from laboratory concepts to deployable covert communication systems for defense, space, and critical infrastructure applications.
