60-Gbit/s THz Communication Hybrid Propagation Through Hollow-Core Fiber and Over the Air
Abstract
This article demonstrates a first time proof of concept for a hybrid approach with hollow-core THz fiber and over-the-air (OTA) propagation for non-line-of-sight (NLOS) THz networks. A 17 cm length of bent antiresonant hollow-core cyclo-olefin (TOPAS) THz fiber was utilized in a 1.87 m NLOS 250 GHz beam path. A maximum 60 Gb/s data rate using 64 QAM modulation with 2.4 x 10-2 bit error ratio (BER) was achieved. This 6G proof-of-concept demonstration potentially leads to follow-on material and fabrication refinements and frequency optimizations for the fiber, and to techniques to focus the THz beam onto the fiber with a lens to significantly reduce power losses in the path.
