Ultrabroadband on-chip photonics for full-spectrum wireless communications.

ABSTRACT: The forthcoming sixth-generation and beyond wireless networks are poised to operate across an expansive frequency range-from microwave, millimetre wave to terahertz bands-to support ubiquitous connectivity in diverse application scenarios^1-3. 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 management⁴. However, existing electrical or photonic-assisted solutions face a lot of challenges in meeting this demand because of the limited bandwidths of the devices and the intrinsically rigid nature of system architectures⁵. Here we demonstrate adaptive wireless communications over an unprecedented frequency range spanning over 100 GHz, driven by
