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 mu m 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. (C) 2019 The Japan Society of Applied Physics
