A novel type of optical bistable device (OBD) based the Abble theory is proposed, in which the modulation is realized by moving one sinusoidal amplitude grating. When the parameters of this system are chosen properly this system can be a one-channel or two-channel optical bistable device. The mathematical models which describe the optically bistability are obtained. Numerical simulations on the optical bistabilities and the stability analysis on this system for two cases are given. The two-channel OBD may work as a 1 × 2 optical switch or a stable filter for wavelength division multiplexing, and may be applied in code-division multiple access networks and optical recovery circuit. © 1994.
