AI总结:

本研究分析了兼具耗散与色散耦合的Fabry-Perot腔光力学系统,发现其共振泵浦下可产生纯耦合不具备的光学刚度,可实现优于SQL的微力检测及更宽参数范围的可控光压挤压。

摘要:

本文对同时具有耗散与色散光机耦合的Fabry-Perot(法布里-珀罗)腔进行了分析。研究证实,这种组合耦合会产生光学刚度。同时,该刚度出现在共振泵浦下具有组合耦合的系统中,这在纯色散耦合和纯耗散耦合中并不典型。本文提出利用该系统检测微小信号力,其灵敏度优于标准量子极限(SQL)。研究还表明,与采用色散耦合的光压挤压相比,该光力学系统可在更宽范围内实现参数可控的光压挤压。

英文摘要:

An analysis is given for the Fabry-Perot cavity having a combination of dissipative and dispersive optomechanical coupling. It is established that the combined coupling leads to optical rigidity. At the same time, this rigidity appears in systems with the combined coupling on the resonant pump, which is not typical for pure dispersive and dissipative couplings. A proposal is made to use this system to detect small signal forces with better sensitivity than SQL. It is also demonstrated that this optomechanical system can create ponderomotive squeezing with controllable parameters over a wider range than ponderomotive squeezing using dispersive coupling.
