Phase noise of THz wave generated by a combination of microresonator soliton comb with uni-traveling-carrier photodiode

TL;DR: In this paper , the phase noise of CW-THz wave at 560 GHz was evaluated with a single uni-traveling-carrier photodiode (UWC).
Abstract: Optical-to-THz conversion of microcomb with uni-traveling-carrier photodiode is a potential method to generate CW-THz wave with ultra-high frequency, low phase noise, and high practicability. In this paper, we evaluated the phase noise of CW-THz wave at 560 GHz.

TL;DR: In this paper, a microwave generator based on a high-Q optical resonator and a frequency comb functioning as an optical-to-microwave divider was demonstrated, with a fractional frequency instability of ≤ 8 × 10−16 at 1 s.
Abstract: Researchers demonstrate a microwave generator based on a high-Q optical resonator and a frequency comb functioning as an optical-to-microwave divider. They generate 10 GHz electrical signals with a fractional frequency instability of ≤8 × 10−16 at 1 s.
