【摘要】：提出一个杂化腔光力系统理论方案,利用两纳米机械振子间的库仑耦合作用实现弱探测光的双光力诱导透明窗口.研究边带可分辨区域和红失谐情况下双光力诱导透明窗口的可调特性.数值计算表明:两纳米振子间的库仑作用可有效地使单光力诱导透明窗口劈裂为双透明窗口.随着库仑耦合强度的增大,两透明窗口间的距离对称性地拉大;其次,光力腔衰减率的改变对两透明窗口的位置和深度无影响,仅对两透明窗口的宽度产生细微改变,测量精度可在坏腔情形下得到很好的保持;另外,仅增加参量放大器的非线性增益参量将使两透明窗口变宽,而引入驱动参量放大器的光场相位,利用相位匹配可以产生比空腔情形更加狭窄陡峭的双透明窗口,可用于比空腔情况更加精密的测量.
[Abstract]:A theoretical scheme of hybrid cavity optical force system is proposed in this paper. Using the Coulomb coupling between two nanometer-sized mechanical oscillators, a double optoforce-induced transparent window of weak probe light is realized. The tunable properties of transparent window induced by double light force in the case of sideband discernible region and red detuning are studied. The numerical results show that the Coulomb interaction between the two nanoscale oscillators can effectively split the transparent window into two transparent windows induced by single light force. With the increase of the Coulomb coupling strength, the distance between the two transparent windows increases symmetrically. Secondly, the change of the attenuation rate of the optical cavity has no effect on the position and depth of the two transparent windows, but only slightly changes the width of the two transparent windows. The measurement accuracy can be maintained well in the case of bad cavity. In addition, only increasing the nonlinear gain parameter of the parametric amplifier will widen the two transparent windows and introduce the optical field phase of the driving parametric amplifier. The use of phase matching can produce a more narrow and steep double transparent window than the cavity case, which can be used for more precise measurement than the cavity case.
