Abstract
Excitation of single guided modes in a multimode graded-index optical fiber has been demonstrated. A side launch technique is employed which permits external selection of input conditions to match the axial and tangential wavenumber components of individual modes. Good agreement is obtained between observed mode order numbers and order numbers calculated from input parameters.Keywords
