Abstract
The simulation for optical characteristics of optical fibers is an important key technology in optical fiber research, and development and manufacturing. Among them, though the micro-bending loss and Rayleigh scattering loss are extremely important characteristics, it is difficult to predict these characteristics with simulations due to the complex phenomena. In these respects, for the micro-bending loss, we developed a new simulation method which combines the mechanical effects and the optical effects by using the coupled mode theory, and regarding Rayleigh scattering, we also developed a method for finding changes in the glass-membered ring structure distribution by using molecular dynamic (MD) simulations. And we have successfully studied various characteristics to be reported.
