论文摘要
随着光学机学领域的发展，二次分散耦合（QDC）有望成为日益可行的定性新功能。但是，领先的QDC几何形状也会产生线性耗散耦合，以及对QDC应用有害的相关量子辐射力噪声。在这里，我们提出了一种简单的修改，该修改大大降低了这种噪声而不会改变QDC强度。我们确定了最佳的操作方案，并在光悬浮和无损声子测量的示例中讨论了优势。
As the field of optomechanics advances, quadratic dispersive coupling (QDC) promise an increasingly feasible class of qualitatively new functionality. However, the leading QDC geometries also generate linear dissipative coupling, and an associated quantum radiation force noise that is detrimental to QDC applications. Here, we propose a simple modification that dramatically reduces this noise without altering the QDC strength. We identify optimal regimes of operation, and discuss advantages within the examples of optical levitation and nondestructive phonon measurement.
