摘要:

低维物体在腔光学力学领域中的使用受到与光学腔模式的尺寸相比其低散射截面的限制。基于光纤的法布里-珀罗微腔可以具有微小的模式截面,并且仍然保持高精细度,增强了光-物质相互作用,从而能够灵敏地检测微小物体的位移。在这里,我们提出了这样一个超灵敏的微腔设置与最高的精细度迄今为止报道的加载光纤腔,$\mathcal{F} = 195\,000$。我们能够定位调谐的静态光机耦合到氮化硅膜条,达到频率牵引参数高达$\mathrm{\lvert G/2π\rvert=1}\,\mathrm{GHz\, nm^{-1}}$。我们还证明了辐射压力的反作用在制度的一个pronounesse高达$\mathcal{F}=165\,000$。

英文摘要:

The use of low-dimensional objects in the field of cavity optomechanics is limited by their low scattering cross section compared to the size of the optical cavity mode. Fiber-based Fabry-Pérot microcavities can feature tiny mode cross sections and still maintain a high finesse, boosting the light-matter interaction and thus enabling the sensitive detection of the displacement of minute objects. Here we present such an ultrasensitive microcavity setup with the highest finesse reported so far in loaded fiber cavities, $\mathcal{F} = 195\,000$. We are able to position-tune the static optomechanical coupling to a silicon nitride membrane stripe, reaching frequency pull parameters of up to $\mathrm{\lvert G/2π\rvert=1}\,\mathrm{GHz\, nm^{-1}}$. We also demonstrate radiation pressure backaction in the regime of an ultrahigh finesse up to $\mathcal{F}=165\,000$.
