Modeling the Concentration Dependence for Manufacturing Single-Mode I/O Structures of MMI-Based Splitters in Thin Glass Sheets

Integrated optical interconnect systems are getting higher attention due to continuously increasing data rates in computer systems. For the realization of these systems, optical waveguide components are needed. One possible approach to manufacturing graded-index waveguide components is their embedding in thin glass sheets by thermal diffusion processes. In this work, the constraints imposed by the manufacturing process for the realization of single-mode input and output structures in multimode-interference-based (MMI-based) optical splitters are elaborated. Fundamental correlations between these constraints and the corresponding modeling of the devices are established.
