  A Kerr microresonator frequency comb has enabled the generation of
low-phase-noise millimeter- and terahertz-waves in conjunction with an
ultrafast photodiode. It is intriguing to employ the new light source in
wireless communication at above 100 GHz band, where a carrier signal with a
high signal-to-noise ratio is desired to achieve higher data rates. In this
study, we demonstrate two simple and efficient architectures of wireless links
based on a microresonator comb. We show experimentally that simultaneous
modulation and detection of multiple comb lines result in >10 times stronger
modulation signal strength than two-line detection at a receiver. Successful
transmission of complex modulation format up to 64 quadrature amplitude
modulation proves that a microresonator comb and the proposed modulation method
are effective in modern wireless communication.
