Paper Abstract

This paper presents a general interference formula described the interference pattern of multi-elliptical core optical fiber in a transverse interferometer. This formula with Mach- Zehnder interferometry is used to characterize multi- elliptical core optical fiber via its refractive index measurement. A CCD camera for further automatic processing and analysis captures the interference pattern of the output field of the Mach-Zehnder interferometry by the computer-aided system. This study gives possibility to analyze optical properties and possible optical and geometrical microdefects of multi-core optical fiber. Example of application to identical nine-elliptical core optical fiber of thickness 380 micrometer fibers is given.
