A theoretical study of bistability in a two-coupler optical fiber ring resonator is presented. The bistability is caused mainly by the degenerate two-wave mixing in which the circulating intensity of the fiber ring depends on the intensity ratio of the signal to the pump beams. The dependence of the bistability on various parameters of the fibers and the couplers is investigated.

On the existence condition for bistability in a one‐coupler optical fiber ring resonator by using degenerate two‐wave mixing

Y. H. Ja

Abstract The existence condition for bistability, B2G > 1, in a one‐coupler single‐mode optical fiber ring resonator using two different all‐fiber schemes of degenerate two‐wave mixing (DTWM) is studied in detail. It is shown that the existence condition for bistability is in general a necessary condition only, not a sufficient condition for the occurrence of the DTWM bistability. © 1994 John Wiley & Sons, Inc.
