摘要:

在这项工作中,我们报告的光机械耦合,解决边带和声子激射在一个固体芯微瓶谐振器上的单模光纤。在机械频率f_m=33.7 MHz和f_m=58.9 MHz下,观察到品质因数(Q_m)分别高达1.57*10^4和1.45*10^4的机械模式。最大f_m*Q_m~0.85*10^12 Hz接近于在室温下克服机械运动的解析边带冷却的热退相干所需的理论下限6*10^12 Hz,这表明微瓶谐振器作为这种努力的可能平台。除了光学机械效应,散射诱导的模式分裂和振铃现象,这是典型的高品质的光学谐振,也观察到在微瓶谐振器。

英文摘要:

In this work, we report optomechanical coupling, resolved sidebands and phonon lasing in a solid-core microbottle resonator fabricated on a single mode optical fiber. Mechanical modes with quality factors (Q_m) as high as 1.57*10^4 and 1.45*10^4 were observed, respectively, at the mechanical frequencies f_m=33.7 MHz and f_m=58.9 MHz. The maximum f_m*Q_m~0.85*10^12 Hz is close to the theoretical lower bound of 6*10^12 Hz needed to overcome thermal decoherence for resolved-sideband cooling of mechanical motion at room temperature, suggesting microbottle resonators as a possible platform for this endeavor. In addition to optomechanical effects, scatter-induced mode splitting and ringing phenomena, which are typical for high-quality optical resonances, were also observed in a microbottle resonator.
