Seamless Convergence Between Terahertz Radios and Optical Fiber Communication Toward 7G Systems
IEEE Journal of Selected Topics in Quantum Electronics(2023)
摘要
Seamless conversion techniques between terahertz radio and optical fiber communication systems are in high demand for future access networks with a low carbon footprint. Radio-over-fiber technologies are a promising solution for realizing conversion in the millimeter-wave and terahertz bands using advanced optical modulation and photodetection devices. Herein, we briefly introduce radio-over-fiber technologies that enable applications to access networks in the seventh-generation mobile (7G) system era. Low-noise and high-frequency oscillator configurations using photonics, which are utilized in terahertz transceivers, are also investigated. A future system integrated with fixed wireless terahertz radio is discussed concerning geographical issues under severe weather conditions.
