Abstract

Numerical studies of gradient index optical splitters made using a multimode interference technology are presented. Multimode interference structures produced in K⁺ to or from Na⁺ and Ag⁺ to or from Na⁺ ion exchange processes have been compared. The influence of geometrical parameters of multimode interference structure and technological process parameters is examined in numerical simulations. Based on the above, gradient index optical waveguide splitters and Mach-Zehnder interferometers in multimode interference configuration are proposed.
