Terahertz wave generated by photomixing of dual-wavelength laser lights injection-locked to a 560-GHz-spacing soliton microcomb for THz wireless communication

Photomixing of internal mode beat in optical comb is a potential method to generate low phase noise CW-THz wave for next-generation wireless communication. Here, we generated a 560-GHz THz wave by photomixing of dual-wavelength near-infrared laser lights injection-locked to a 560-GHz-spacing soliton microcomb with a uni-traveling-carrier photodiode. Then, we apply the generated THz waves for THz wireless communication.
