Abstract :
Short (1¿400 m) multimode fibres were excited by a single-mode fibre. The resulting near-field intensity distributions are generally not circularly symmetric. A calculation based on ray optics shows that slightly elliptical fibres give similar distributions. This calculation assumes a central index-profile dip.
