This study successfully captures the dissipative Kerr solitons generated in a crystalline optical microresonator using the phase-modulation-induced potential gradient technique, and achieves side-mode suppression of the microwave signal through photodetection. The hybrid system simultaneously produces a drift-reduced microcomb and a spectrum-purified optoelectronic oscillator, providing a low-cost solution for microwave and optical metrology.
Using phase-modulation-induced potential gradient whose period is synchronized to a microwave opto-electronic oscillator, dissipative Kerr solitons generated in a crystalline optical microresonator are trapped by the soliton tweezing effect, exhibiting a stabilized soliton repetition rate. In the meantime, side-mode suppression of the microwave signal is enabled by the photodetection of the soliton train. Substantiated both experimentally and theoretically, the hybrid system produces a drift-reduced microcomb and a spectrum-purified optoelectronic oscillator simultaneously, yielding a low-cost toolkit for microwave and optical metrology.
