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

Abstract

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.

Kerr bistability in a 3 × 3 coupler optical fiber ring resonator

Y. H. Ja

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.

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

Y.H. Ju

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.>

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.

Kerr-effect-induced S–R flip-flop operation in an optical fiber loop resonator with double couplers

Takehiro Fukushima, Toyokazu Sakamoto

We carry out a theoretical analysis of Kerr bistability in a double-coupler optical fiber loop resonator in a case of two coexisting input optical fields, and we propose a set-reset (S-R) flip-flop operation that uses two input ports. We found that in the optimum case set and reset operation can be achieved at relatively low optical input powers.

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

Y. H. Ja

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.
