Abstract

In recent years, the concept of hyperbolic phonon polaritons (HPPs) has revolutionized the field of nanophotonic, enabling unprecedented control over light-matter interactions at the nanoscale. Here, we theoretically propose and study the lateral optical forces in twisted mixed-dimensional MoO3 homostructures. Assisted with the low-symmetry hyperbolic phonon polaritons, we realized a lateral optical force exerted on the Au nanoparticle near the surface of mixed-dimensional MoO3 homostructures with a linear polarized incident light. By controlling the polarization state, incident angle of light and the twisted angle of MoO3, the amplitude and direction of the lateral optical forces can be tailored in the mid-infrared range. Our findings provide a new platform for engineering lateral optical forces to manipulate diverse objects in a flexible and efficient manner.
来自扭曲的混合维 MoO3 同质结构的可配置横向光学力
近年来,双曲声子极化子(HPPs)的概念彻底改变了纳米光子领域,使人们能够在纳米尺度上对光与物质的相互作用进行前所未有的控制。在这里,我们从理论上提出并研究了扭曲的混合维 MoO3 同质结构中的横向光学力。在低对称性双曲声子极化子的辅助下,我们实现了线偏振入射光对混合维 MoO3 同质结构表面附近的金纳米粒子施加横向光学力。通过控制偏振态、光的入射角和 MoO3 的扭曲角,横向光学力的振幅和方向可以在中红外范围内进行定制。我们的研究成果为横向光学力工程学提供了一个新平台,可以灵活有效地操纵各种物体。
