title: Tunneling-induced optical bistability in an asymmetric double quantum well.
abstract: Optical bistable behaviors induced by tunneling coupling are demonstrated in an asymmetric double quantum-well structure including a unidirectional ring cavity. We analytically find that optical bistability can be obtained with the existence of resonant tunneling. Furthermore, the threshold of the optical bistability can be modulated by the intensity or the detuning of the driving fields.
