This paper shows the demonstration of Multimode Interference (MMI) power splitters with graded index waveguides using ion-exchange technology. Typically these devices have been fabricated using step index waveguides such as silica waveguides on silicon. The advantages of ion-exchange technology and MMI splitters fabricated by ion-exchange are discussed. The design and simulation results for a 1 * 4 MMI splitter are presented and compared to the experimental results.
