Abstract
We present what is to our knowledge the fast experimental observation by fl uorescent visualization, of the evolution of the mode field profile in a pe riodically segmented waveguide. The experimental observations are then comp ared with the numerical results obtained by a finite-difference beam propag ation method. Good agreement between experimental and numerical results is observed. (C) 1999 Optical Society of America OCIS codes: 130.0130, 130.279 0, 230.7380, 350.550, 200.2510.
