论文摘要
通过在光学微孔子中生成Brillouin激光器，我们使用同一腔中生成的Brillouin激光器通过激发Kerr频率梳子实现了Soliton Kerr Microcomb。腔内布里远激光抽水方案使我们能够使用蓝色的输入泵进入孤子状态。由于产生的Brillouin激光器的超鼻涕线宽和低噪声性能，即使使用二极管激光器，观察到的孤子微量梳也表现出狭窄的线宽梳子和稳定的重复速率，即使使用具有相对较宽的线宽的二极管激光。另外，我们在10 Hz时表现出一个低噪声微波信号，相位噪声水平为-24 dbc/hz，在10 kHz时为-111 dbc/hz，为11.14 GHz载体时，在1 MHz偏移量为1 MHz时为-147 dbc/hz，只有一个免费输入泵。 Brillouin-Kerr Soliton Microcomb具有出色性能的轻松操作使我们的计划有望实用。
By generating a Brillouin laser in an optical microresonator, we realize a soliton Kerr microcomb through exciting the Kerr frequency comb using the generated Brillouin laser in the same cavity. The intracavity Brillouin laser pumping scheme enables us to access the soliton states with a blue-detuned input pump. Due to the ultra-narrow linewidth and the low-noise properties of the generated Brillouin laser, the observed soliton microcomb exhibits narrow-linewidth comb lines and stable repetition rate even by using a diode laser with relatively broad linewidth. Also, we demonstrate a low-noise microwave signal with phase noise levels of -24 dBc/Hz at 10 Hz, -111 dBc/Hz at 10 kHz, and -147 dBc/Hz at 1 MHz offsets for a 11.14 GHz carrier with only a free-running input pump. The easy operation of the Brillouin-Kerr soliton microcomb with excellent performance makes our scheme promising for practical applications.
