Optical bistability in a one planar 3 × 3 coupler fiber‐ring resonator with degenerate two‐wave mixing

Abstract
Abstract A theoretical study of optical bistability in a Type 1 one (planar 3 × 3) coupler fiber‐ring resonator with an all‐fiber scheme, Scheme B, of degenerate two‐wave mixing (DTWM) is presented. The bistability is caused by the DTWM, the inherent positive feedback in the fiber‐ring resonator and the nonlinear dependence of the circulating intensity of the fiber‐ring resonator on the DTWM gain. The relations between the bistability and various parameters of the fibers and the planar 3 × 3 coupler are inuestigated. A comparison between the bistability in such a jiber‐ring resonator and that using an equilateral triangular 3 × 3 fiber coupler is also made. © 1994 John Wiley & Sons, Inc.
