Abstract
A spatial coherence analysis of light propagation in optical fibers illuminated with a laser source is presented. Modulus and phase of the complex degree of spatial coherence across the end cross section are measured by means of Michelson-type wave-front-reversing interferometry. Interference fringe patterns of a laser beam emerging from the output end of optical fibers are also photographed. Comparison of the measurement with theory enables us to characterize the modal content in a quasi-single-mode fiber.
