光子在晶格上产生磁场的光机方法

Optomechanical creation of magnetic fields for photons on a lattice

M. Schmidt, S. Keßler, V. Peano, O. Painter, F. Marquardt

摘要:

我们提出利用光机械相互作用在晶格上产生光子的人工磁场。所需的成分是光学机械晶体,即一块具有正确孔图案的电介质,以及两束具有正确相位图案的激光束。两个方案之一是基于光学模式之间的链接的光机械调制,而另一个是光机械波长转换设置的晶格扩展。我们说明了由此产生的光谱,光子输运在人工洛伦兹力的存在下,边缘状态,和光子Aharonov-Bohm效应。此外,我们还简要地描述了作用于与声子/光子自由度有关的综合维数的规范场。这些可以使用撞击在光学机械阵列上的单个激光束来生成。

英文摘要:

We propose using the optomechanical interaction to create artificial magnetic fields for photons on a lattice. The ingredients required are an optomechanical crystal, i.e. a piece of dielectric with the right pattern of holes, and two laser beams with the right pattern of phases. One of the two proposed schemes is based on optomechanical modulation of the links between optical modes, while the other is an lattice extension of optomechanical wavelength-conversion setups. We illustrate the resulting optical spectrum, photon transport in the presence of an artificial Lorentz force, edge states, and the photonic Aharonov-Bohm effect. Moreover, wWe also briefly describe the gauge fields acting on the synthetic dimension related to the phonon/photon degree of freedom. These can be generated using a single laser beam impinging on an optomechanical array.
