Analysis of fields and coupling associated with optical fibers with power-law profiles

The fundamental mode fields of optical fibers are of importance for various applications. The field and relevant properties are directly related to the index profile of the fiber itself. In practice, index profiles for many fibers can be represented by power-law functions. Within the framework of a field approximation method the authors systematically study fundamental mode fields of optical fibers with clad power-law profiles, as well as coupling occurring between two such fibers.<
