COUPLER-LOSS AND COUPLING-COEFFICIENT DEPENDENCE OF BISTABILITY AND INSTABILITY IN A FIBER RING RESONATOR: NONLINEAR BEHAVIORS

Preecha P. Yupapin, P. Saeung, W. Suwancharoen

In this paper we demonstrate the dynamic simulation of light traveling in a nonlinear fiber optic ring resonator (FORR) with a single coupler. The mathematical relations describing the nonlinear characteristics of the FORR are derived from light transmission theory in linear optical systems. Optical nonlinear phenomena such as bifurcation and chaos are investigated for optical bistability and the Ikeda instability. It is found that for the Ikeda instability of light inside a FORR, the ring-cavity lifetime is much longer than the Kerr-effect response time of the fiber ring. Transmission curves of bistability and instability are shown as a function of the coupler insertion losses (γ) and the coupling coefficients (κ).

Quantum chaotic signals generated by a nonlinear micro-ring resonator

Chatchawal Sripakdee, W. Suwancharoen, Preecha P. Yupapin

This paper presents a new concept of quantum-chaotic encoding of light traveling in a fiber optic ring resonator. The Kerr nonlinear effects type of light in a fiber optic ring resonator is induced, and the four-wave mixing of the propagating waves at resonance occurred. The output signals can generate the double security which one is the quantum bits i.e. code, and the other is the chaotic signal/code. The proposed system has shown the potential of using for communication security, where the double security via the quantum-chaotic encoding can be performed.
