我们研究石墨烯纳米带之间的高光限制、场增强和强梯度力。提出了入射光波长对梯度力的影响，这在以前的研究中是罕见的。取得了比基于人工双曲超材料的槽波导更好的光场限制效果。传播长度和增强比分别可达79.5 μm和16。值得一提的是，光限制率可以达到惊人的97%。最后，我们从电场角度分析不同强度的梯度力。
We study high light confinement, field enhancement, and strong gradient force between graphene nanoribbons. Influence of the wavelength of incident light on the gradient force, which is rare in previous studies, is presented. Results of light field confinement are achieved, which are much better than those in the slot waveguides based on artificial hyperbolic metamaterials. The propagation length and enhancement ratio can be up to 79.5 μm and 16, respectively. It is worth mentioning that the light confinement ratio can reach an astonishing 97%. Finally, we analyze the gradient force of different intensity in terms of the electric field.
