论文摘要
提出了一种远程弱信号传感器的方案，其中耦合谐振器光学波导〜（crow）作为发射器，分别伴侣与混合的光学腔和观测腔。通过将乌鸦视为腔场的非马克维亚储层，并引入了非马克维亚理论来研究弱力传感器，并引入负面效应的质量〜（NEM）振荡器来消除反作用噪声。在某些条件下，可以形成无耗散的结合状态，以使弱信号可以在乌鸦中转移而不会耗散。我们的结果表明，在某些参数制度下，可以在结合状态的帮助下实现超高灵敏度。
A scheme for remote weak signal sensor is proposed in which a coupled resonator optical waveguide~(CROW), as a transmitter, couples to a hybrid optomechanical cavity and an observing cavity, respectively. The non-Markovian theory is employed to study the weak force sensor by treating the CROW as a non-Markovian reservoir of the cavity fields, and the negative-effective-mass~(NEM) oscillator is introduced to cancel the back-action noise. Under certain conditions, dissipationless bound states can be formed such that weak signal can be transferred in the CROW without dissipation. Our results show that ultrahigh sensitivity can be achieved with the assistance of the bound states under certain parameters regime.
