在这篇文章中,我们描述了如何开发一个模式转换器,将平面电磁波转换为向内移动的偶极子波。后者的目的是使一个原子或离子从其基态到激发态的单光子波包的吸收效率接近100%。
In this article, we describe how to develop a mode converter that transforms a plane electromagnetic wave into an inward-moving dipole wave. The latter one is intended to bring a single atom or ion from its ground state to an excited state by absorption of a single photon wave packet with near-100% efficiency.
