Optical frequency division (OFD) through an optical frequency comb has been employed for generating microwave signals with extraordinary phase noise performance. Although its extension to millimeter and terahertz wave domain is of great interest for applications such as rotational spectroscopy and wireless communication, the demonstration is hindered by necessity of ultrafast optoelectronic devices and performing self-referencing with high repetition rate pulses. In this study, we demonstrate OFD of an optically-carried 3.6 THz reference via an integrated dissipative Kerr soliton comb, and generate a 300 GHz wave with a record-low phase noise of −100 dBc/Hz at 10 kHz Fourier frequency.
