【摘要】：提出一個(gè)雜化腔光力系統(tǒng)理論方案,利用兩納米機(jī)械振子間的庫侖耦合作用實(shí)現(xiàn)弱探測光的雙光力誘導(dǎo)透明窗口.研究邊帶可分辨區(qū)域和紅失諧情況下雙光力誘導(dǎo)透明窗口的可調(diào)特性.數(shù)值計(jì)算表明:兩納米振子間的庫侖作用可有效地使單光力誘導(dǎo)透明窗口劈裂為雙透明窗口.隨著庫侖耦合強(qiáng)度的增大,兩透明窗口間的距離對稱性地拉大;其次,光力腔衰減率的改變對兩透明窗口的位置和深度無影響,僅對兩透明窗口的寬度產(chǎn)生細(xì)微改變,測量精度可在壞腔情形下得到很好的保持;另外,僅增加參量放大器的非線性增益參量將使兩透明窗口變寬,而引入驅(qū)動(dòng)參量放大器的光場相位,利用相位匹配可以產(chǎn)生比空腔情形更加狹窄陡峭的雙透明窗口,可用于比空腔情況更加精密的測量.
[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.
