Optical chaos communication and key distribution have been extensively demonstrated with
high-speed advantage but only within the metropolitan-area network range of which the …

We propose and experimentally study a coherent optical secure transmission system based
on one dual-polarization in-phase and quadrature modulator (IQM). One beam of the …

This study proposes a physical layer encryption scheme based on disturbance of data
cluster under color seeking mechanism of chaotic sequence which is generated by …

Chaotic optical communication has shown large potential as a hardware encryption method
in the physical layer. As an important figure of merit, the bit rate–distance product of chaotic …

In the 5G era, more sensitive information will be transmitted on optical networks. Although
modern cryptography could support different security mechanisms in different layers, the …

Simultaneous generation and synchronization of multiple broadband laser chaos with
different wavelengths are numerically demonstrated by using long-active-cavity Fabry-Perot …

For next-generation high-capacity, rate-flexible, and secure 400-G passive optical network
(PON), a scheme joint wavelength division-multiplexed (WDM), entropy-regulated …

In recent years, the transmission capacity of chaotic secure communications has been
greatly expanded by combining coherent detection and multi-dimensional multiplexing …

We numerically investigate the effects of probabilistic shaping on the performance
improvement of coherent optical chaos communication. Results show that the decryption bit …

Amplified spontaneous emission (ASE) light is the most natural optical carrier to hide a
message in the existing optical networks at photonic layer. To enhance the anti-intercept …
