Terahertz Communications in Photonics

Dear Colleagues,

We are pleased to invite you to contribute to the upcoming Special Issue of Photonics titled “Terahertz Communications in Photonics”. With the rapid development of 6G wireless networks and beyond, the demand for ultra-high-speed and ultra-broadband communication systems has become more pressing than ever. Terahertz (THz) communication, benefiting from the ultra-wide bandwidth available in the THz spectrum (0.1–10 THz), has emerged as a key technology in efforts to meet these demands. However, practical implementation faces significant challenges, including high propagation loss, hardware limitations, and signal processing complexity.

Photonics-assisted THz technologies offer a promising route to overcome these limitations, leveraging the advantages of optical carriers for signal generation, modulation, transmission, and detection. This interdisciplinary area is attracting increasing attention from researchers in both photonics and wireless communication communities, driving innovation in THz signal generation, photonic integration, sensing, and system-level design.

This Special Issue aims to provide a comprehensive platform, presenting the latest advances in photonics-enabled THz communications, bridging the gap between theory, devices, and systems. The scope of this publication with the journal’s focus on photonic devices, systems, and applications, and seeks to highlight cutting-edge research that enables THz wireless communication through photonic techniques.

Original research articles and review papers are welcome. Topics of interest include, but are not limited to, the following areas:

• Photonic generation and detection of THz signals;
• Integrated photonic circuits for THz communication systems;
• Hybrid optical-wireless (fiber–THz) communication links;
• High-speed signal processing and modulation schemes for THz;
• Terahertz-over-fiber and photonics-assisted front-haul networks;
• THz antennas and beamforming supported by photonics;
• Experimental demonstrations of photonics-enabled THz links;
• Applications of THz communications in sensing and imaging;
• Photonic solutions to overcome THz propagation challenges.

We look forward to receiving your contributions.
