Abstract
The forthcoming sixth-generation (6G) and beyond (XG) wireless networks are poised to operate across an expansive frequency range from microwave, millimeter-wave to terahertz bands to support ubiquitous connectivity in diverse application scenarios. This necessitates a one-size-fits-all hardware solution that can be adaptively reconfigured within this wide spectrum to support full-band coverage and dynamic spectrum management. However, existing electrical or photonic-assisted wireless communication solutions see significant challenges in meeting this demand due to the limited bandwidths of individual devices and the intrinsically rigid nature of their system architectures. Here, we demonstrate adaptive wireless communications over an unprecedented frequency range spanning over 100 GHz, driven by a universal thin-film lithium niobate (TFLN) photonic wireless engine. Leveraging the strong…
