| 摘 要： | Optical bistability(OB) is capable of rapidly and reversibly transforming a parameter of an optical signal from one state to another, and homologous nonlinear optical bistable devices are core components of high-speed all-optical communication and all-optical networks. In this paper, we theoretically investigated the controllable OB from a Fabry–Pérot(FP) cavity with a nonlinear three-dimensional Dirac semimetal(3D DSM) in the terahertz band. The OB stems from the third-order nonlinear bulk cond...
