Zeyang Liao, M. Al-Amri, M. Suhail. Zubairy

摘要:

在波导量子电动力学(QED)系统中,发射极分离对系统的功能起着重要的作用。在这里,我们提出了一种方法来测量深亚波长发射极分离的波导QED系统。在这种方法中,我们还可以确定一个衍射极限光斑内的发射器的数量。此外,我们还表明,超小的发射极分离的变化,可以检测到在这个系统中,然后可以用作波导QED为基础的传感器来测量微小的局部温度/应变变化。

英文摘要:

In the waveguide quantum electrodynamics (QED) system, emitter separation plays an important role for its functionality. Here, we present a method to measure the deep-subwavelength emitter separation in a waveguide-QED system. In this method, we can also determine the number of emitters within one diffraction-limited spot. In addition, we also show that ultrasmall emitter separation change can be detected in this system which may then be used as a waveguide-QED-based sensor to measure tiny local temperature/strain variation.
