16. A. Tomasino, A. Shams-Ansari, M. Loncar, I.-C. Benea-Chelmus, “Large area photonic circuits for terahertz detection and beam profiling“, arxiv.org/abs/2410.20407

Alessandro and team demonstrate plug-and-play coherent terahertz detectors at 500 GHz, a 6G band. They argue that the low loss of thin film lithium niobate platform is a key asset to enable integration of  a two-dimensional array of terahertz antennas with the photonic circuit to conceptualize, implement and demonstrate selectivity to this desired 6G band through a novel type of quasi-phase matching, robustness to illumination and beam profiling capabilities.
