Modeling Multivariate Dependencies for Manufacturing Single-Mode I/O Structures of Integrated MMI-Based Splitters in Glass Sheets

For the realization of integrated optical interconnect systems, optical waveguide components are needed. A promising approach to manufacturing graded-index waveguide components is their embedding in thin glass sheets by ion-exchange processes. In this work, constraints imposed by the multivariate manufacturing process for the realization of single-mode input and output structures in multimode-interference-based (MMI-based) optical splitters are elaborated. Corresponding correlations between these constraints and the according modeling of the devices are established.
