摘要:

箝位损耗限制了由支撑杆支撑的光机械谐振器中的机械模式的品质因数。利用连续介质中的机械束缚态,我们发现可以避免机械夹持损失。微球的机械品质因数可以实现高达10^8的杆的特定半径,其中谐振器和支撑杆之间的不同耦合通道彼此正交。该机构对不同的几何形状和材料具有通用性,可推广应用于高质量机械谐振器的设计。

英文摘要:

Clamping loss limits the quality factor of mechanical mode in the optomechanical resonators supported with the supporting stem. Using the mechanical bound state in the continuum, we have found that the mechanical clamping loss can be avoided. The mechanical quality factor of microsphere could be achieved up to 10^8 for a specific radius of the stem, where the different coupling channels between the resonator and supporting stem are orthogonal to each other. Such mechanism is proved to be universal for different geometries and materials, thus can also be generalized to design the high quality mechanical resonators.
