Vincent Dumont, Hoi-Kwan Lau, Aashish A. Clerk, Jack C. Sankey

摘要:

随着光力学领域的进步,二次色散耦合(QDC)承诺一个越来越可行的一类定性的新功能。然而,领先的QDC几何形状也产生线性耗散耦合,以及相关的量子辐射力噪声,这对QDC应用是不利的。在这里,我们提出了一个简单的修改,大大降低了这种噪声,而不改变QDC的强度。我们确定的最佳制度的操作,并讨论内的光学悬浮和无损声子测量的例子的优势。

英文摘要:

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.
