Linear and nonlinear behavior in single-ring resonators

This study has been focused on the linear and nonlinear behavior and investigative in single-ring resonator. Optical fiber ring resonators have great interest due to different applications, especially in communication, secured communication, slow light, fast light and light storage in optical buffers. There are many proposed applications of optical ring resonators. Optical fiber ring resonators can be readily constructed from standard optical fiber components, which allow their properties to be studied in a systematic manner. In this paper, we describe our studies of the optical transmission, intensity, shift phase and group delay characteristics of a family of such devices. In this case, Gaussian beam has been used as an input pulse inside to microring resonators. In this paper, transmission, intensity, shift phase and group delay characteristics of device have been investigated. It has been compared together in different coupling coefficients in frame of linear and nonlinear.
