Multiple bistability in an optical-fiber double-ring resonator utilizing the Kerr effect

Abstract

We present a theoretical study of multiple bistability in an optical-fiber double-ring resonator. The multiple bistability is caused by the optical Kerr effect, which modulates the refractive index of the fiber. The dependence of the multiple bistability on various parameters of the fibers and the couplers is investigated.>

We present a theoretical study of bistability in an optical fiber ring resonator connected to a 3 × 3 fiber coupler. The bistability is caused by the Kerr effect when the ring resonator is working in the nonlinear regime. The dependence of the bistability on various parameters of the fiber and the coupler is investigated.

Kerr bistability in an optical fiber ring resonator with a 3 × 3 planar fiber coupler

Y. H. Ja

A theoretical study of bistability caused by the optical Kerr effect in a type 1 optical fiber ring resonator connected to a 3 × 3 planar coupler is presented. The dependence of the bistability on various parameters of the fiber and the coupler is investigated. A comparison between the bistable characteristics of this ring resonator and those of a fiber ring resonator with a 3 × 3 equilateral triangular (nonplanar) fiber coupler is made.

Kerr bistability in optical fiber loop resonators with a 3 × 3 fiber coupler

Y. H. Ja

Abstract A theoretical study of bistability caused by the Kerr effect in two types of optical fiber loop resonators connected to a 3 × 3 coupler is carried out. The dependence of the bistability on various parameters of the fiber and the coupler is investigated and presented as graphs. The bistability offers the possibility of using these fiber loop resonators as optical logic gates, memories, switches, and differential amplifiers. © 1993 John Wiley & sons, Inc.

Optical bistability in a two-coupler fiber ring resonator by using degenerate two-wave mixing

Y. H. Ja

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.

Elimination of Kerr bistability in an optical fiber ring resonator with a 3 × 3 planar fiber coupler

Y. H. Ja

A special property of a type 3 optical fiber ring resonator with a 3 × 3 planar coupler in which the circulating intensity is independent of the phase change of the ring resonator can be used to eliminate unwanted Kerr bistability. At the same time the device can be used as a two-channel frequency division multiplexer or demultiplexer or a switch. Another method for the elimination of Kerr bistability is the use of two fibers whose nonlinear refractive-index coefficients have opposite signs to build the ring resonator.

Kerr Effect in Brillouin Fiber-optic Ringesonator

Wang Jun

Based on the mechanism of Kerr effect in Brillouin Fiber-optic Ring Resonator(BFRR),the resonant cavity characteristic is researched theoretically when considering the Kerr effect,in order to get the possibility of occurrence of first-order Stokes light optical bistability. Experiments show that the optical bistability in 30 meters short cavity happens while input light intensity is about 440 μW,and the bistability is related with coupling coefficient and the insertion loss of the cavity coupler. Secondly,the Kerr effect in BFRR of Brillouin Fiber-optic Gyroscope (BFOG) is analyzed,focusing on the influence of resonant deviation on gyroscope nonlinear output and dynamic working range. Furthermore,the double-loop BFOG program is proposed,which provides a potential solution of Kerr effect error in Brillouin fiber-optic gyroscope.
