ABSTRACT: In this work, we develop a simulation method based on
supermode theory and transfer matrix formalism, and then apply it to the
analysis and design of taper couplers for vertically integrated As2S3 and Ti: LiNbO3 hybrid waveguides. Test structures based on taper
couplers are fabricated and characterized. The experimental results confirm the
validity of the modeling method, which in turn, is used to analyze the
fabricated couplers.
