The paper is concerned with applications of multimode interference structures (MMI) as the elements of integrated optic circuits. Investigations of MMI produced by ion-exchange in glass, obtained by visualization method of light propagation in gradient structures, using fluorescence of the substance covering the MMI section, are presented. Experimental results concern the self-imaging phenomena for symmetrical and paired interference for TE, TM and unpolarized light excitation. On the base of investigations and BPM simulations the applications of MMI are proposed.
