Nonlinearity penalties and benefits of light traveling in a fiber optic ring resonator

The nonlinearity properties of light traveling in a fiber optic ring resonator (FORR) are presented. The nonlinearity penalties suffering from Kerr effects and four-wave mixing nonlinear types including bistability, chaos and bifurcation are investigated. The advantages of the nonlinearity penalties including photon correlation, optical switching and information security using chaotic signals are also discussed. The obtained results have shown that the parameters of FORR can be changed, and thus the penalties of the nonlinear effects have shown the potential of using for some applications.
