Improving Propagation Characteristics In Single-Mode Optical Fibers With Computer-Aided Analysis Using Wave Equation Techniques

The normalized scalar wave equation is solved for propagation parameters which depend on only the normalized frequency V and an arbitrary refractive-index profile. Analytic expressions relate these parameters to the optical fiber diameter, materials, and wavelengths of interest. These expressions are used to find dispersion and bandwidth. In this way it is possible to determine fiber parameters so that minimum dispersion occurs at preferred operating wavelengths. Then refractive-index profiles may be modified to improve bandwidth over desirable ranges.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
