Abstract

This article is devoted to numerical study and application aspects of the Mach-Zehnder interferometer (MZI) design. The MZI operating point position is studied with respect to waveguide topology and waveguide width with beam propagation method. Experimental samples of MZI based on numerical study results are fabricated. Operating point position of five various MZI topologies is measured with experimental set up. Comparison of numerical and experimental results is accomplished.
