Description
Summary:We present the first topological integrated antenna that addresses the persistent challenge of momentum mismatch between chip-based topological edge state and plane wave in free space. The mismatch results from the material impedance inconsistency, hampering the efficient wave radiation and reception of a topological chip. The reported silicon topological waveguide-antenna achieves a 12.2 dBi gain across a 30 GHz bandwidth in 0.3 THz band, ensuring a 100 Gbps inter-chip wireless data communication. The CMOS-compatible topological antenna holds potential applications in hybrid electronic-photonic-based topological wireless communications vital for the future of communication from the sixth to X generation.
