Wireless electronics that have been used thus far in next-generation mobile communications using terahertz waves may reach their technical limit (namely, upper limit of frequency for wireless electronics).
Terahertz wireless communication in the 560-GHz band was achieved by optical-to-electrical conversion of ultra-high-frequency photonic RF signals in near-infrared micro-resonator soliton comb.
Adding the low-phase noise that is characteristic of micro-resonator soliton comb to terahertz waves makes it possible to achieve ultra-high-speed and large-capacity wireless communication using advanced modulation and demodulation of amplitude and phase.
