Special Issue Information
Dear Colleagues,
Optical communication has become one of the most important communication technologies today owing to its outstanding advantages, such as high transmission speed, large information capacity, and long transmission distance. At present, more than 90% of global information communication services are carried out by optical networks, involving various fields of the national economy. With the substantial increase in the transmission rate and capacity of optical networks, the sources of security threats and attack methods are continuously emerging, and network security has recently gained attention as an important strategic issue.
Traditional security technologies in optical fiber communication systems predominantly utilize the cryptographic encryption method to encrypt data at the MAC layer and its upper layer. At the same time, physical layer security is the first barrier to the security of the entire communication system, which is of decisive significance. It is highly challenging for current algorithm-based encryption and physical-layer encryption technologies to meet the development needs of high-speed secure optical systems in terms of security, transmission rate, and compatibility.
A preeminent strategy to improve the physical-layer security of the optical communication system is chaotic phase scrambling, that is, to use the randomness of chaotic signals to implement effective multidimensional noisy encryption of optical information, which can guarantee high-speed and long-distance transmission, and is also flexibly compatible with traditional optical fiber communication systems.
This Special Issue seeks innovative works on a wide range of research topics, spanning both theoretical and systems research, including results from industry and academic/industrial collaborations, related, but not restricted to, the following topics:
- Secure optical communication using chaos technology;
- Optical access networks;
- Semiconductor laser sensor networks;
- Physical entropy source for random bit generation;
- Optical communication using physical layer security techniques;
- Secure key distribution for optical communication;
- Free-space optical (FSO) communication using orbital angular momentum (OAM) multiplexing;
- OAM mode division multiplexed optical fiber communication;
- OAM demultiplexing using machine learning techniques;
- Atmospheric turbulence compensation in FSO communication;
- Compact and high-performance OAM mode generation for optical communication;
- Optical network prediction using reservoir computing;
- Optical sensor network for chaos lidar.
