摘要：

Step-index single-mode optical fibers were tapered and then cleaved by ion beam milling to allow direct examination of the mode evolution in the taper with a microscope objective and CCD camera. Observation of HE1m modes is reported in tapered fibers cleaved at diameters ranging from 8 to 35 mu m. Theoretical scalar mode fields are fit to the experimental data and the mode transitions are explained by considering coupled-mode theory.
