WebIn this paper, we have theoretically investigated the optical tristability with low threshold by constructing a simple double layer graphene structure. The optical tristability mainly originates from the huge third-order nonlinear coefficient of graphene and the suitable structural parameters. WebWe theoretically investigate the behavior of optical bistability (OB) and optical multistability (OM) in a graphene monolayer system driven by an elliptically polarized control field and a right-hand circularly polarized probe field. Our numerical results show that it is easy to realize the transition from OB to OM or vice versa by adjusting the frequency detunings of …
