Search for: [Abstrakt = "The paper presents an analysis of self\-imaging phenomena in gradient multimode interference \(MMI\) structures produced by K\+–Na\+ ion exchange in glass. This investigation concerned curved MMI structures with various geometries – for the linear, concave function described by an exponential function, and the convex structure connected with a cosine course. The relations derived characterizing the relative shortening of the length of propagation for N\-fold images have been confirmed by numerical simulations using the beam propagation method \(BPM\) of symmetrically excited gradient splitters 1×2."]
