Tunable Optical Bistability and Tristability in Nonlinear Graphene-Wrapped Nanospheres

Zhang, Kai; Huang, Y; Miroshnichenko, Andrey; Gao, L


We develop the nonlinear electromagnetic theory (NET) including the self-consistent mean-field approach to investigate the optical multistability of graphene-wrapped dielectric nanoparticles. We demonstrate the optical bistability (OB) of the graphene-wrapped nanoparticle in both near-field and far-field spectra due to electric dipolar modes for small sizes, as predicted in the quasistatic limit (QL). For small sizes, two OB regions can be observed when the magnetic dipolar modes arise under...[Show more]
