Abstract: (2701 Views)
Single-mode operation (SMO) is favorable in most practical applications because of its high mode confinement and low transmission loss. In this paper, we study the dependence of SMO region on the width and operation frequency of a graphene nano-ribbon waveguide (GNRW) using finite-element method. Numerical results show that SMO in GNRW strongly depends on the overall width and operation frequency and SMO can be realized by decreasing the overall width or operation frequency.
Keywords: Finite-element method, Propagation length, Waveguide, Single-mode operation, Graphene nanoribbon
