Abstract
Experimental results obtained by the visualization method of modal interference in gradient-index multimode interference structures made by Ag+-Na+ and K+-Na+ ion exchange process in glass are presented. The investigation concerns the self-imaging phenomena for symmetrical and paired interference for TE, TM and unpolarized light excitation. A comparison between experimental results obtained and beam propagation method (BPM) simulations is also presented.
