Abstract
This paper is concerned with analysis of interference patterns in gradient multimode interference (MMI) structures. Analyzed images presenting self-imaging effects were obtained at experimental arrangement which enables direct observation of modal fields interference using fluorescent cover on MMI sections. Investigated structures were produced by K+ ↔ Na+ ion exchange process in glass. Described analysis contains the quantitative approach to multiple images of input field. The received results concerning the quantitative dependences and geometry of obtained images are presented.
