摘      要：Flexible multiplexing chips that permit reconfigurable multidimensional channel utilization are indispensable for revolutionary 6G terahertz communications,but the insufficient manipulation capability of terahertz waves prevents their practical ***,we propose the first experimental demonstration of a flexible multiplexing chip for terahertz communication by revealing the unique mechanism of topological phase(TP) transition and perseveration in a heterogeneously coupled bilayer valley Hall topological photonic *** synthetic and individual TPs operated in the coupled and decoupled states enable controllable on-chip modular TP transitions and subchannel *** time-frequency interleaved subchannels support 10-and 12-Gbit/s QAM-16 high-speed data streams along corresponding paths over carriers of 120 and 130 GHz with 2.5-and 3-GHz bandwidths,*** work unlocks interlayer heterogeneous TPs for inspiring ingenious on-chip terahertz-wave regulation,allowing functionality-reconfigurable,compactly integrated and CMOS-compatible chips.
