Fiber Optic Communication

Dear colleagues,

Over the last five decades fiber optic communication has been the most important means of human communication. In the coming decades it will continue to play a core role in communication networks. In the future optical fiber communication will have greater bandwidth, higher speed, intelligence, device integration, and photoelectric cooperation to provide large bandwidths and low delay networks for new technologies, such as AR/VR, 5G, 6G, etc. Fiber optic communication is a set of major components, including:

• Fiber optic systems, fiber optic subsystems, and their new applications in quantum electronic devices, including system demonstrations, signal processing, performance characterization, etc.;
• Architecture and design of fiber-based optical networks;
• Architecture and design of free space and hybrid optical networks;
• Smart sensors, such as intelligent optical fiber sensors, spectrum sensors, photoelectric sensors, etc.;
• Active components, such as semiconductor lasers and amplifiers, fiber optic amplifiers, photodetectors, and optical switches;
• Passive optical components, such as silicon and InP, and silica components;
• Fiber, cable, and waveguide technologies, including materials, splicing, connectors, measurement techniques, etc.;
• Signal processes, including technologies related to artificial intelligence, machine learning;
• Radio over fiber, including technologies related to digital/analog linearization, radio frequency/microwave circuits over fiber communication, photoelectric modulators, photoelectric detectors, etc.

This Topic aims to collect the results of research in these and other relevant areas of fiber optic communication. The submission of papers within those areas with strong connection to beyond 5G/6G/THz over fiber applications is strongly encouraged.
