Abstract
This work presents the theoretical results regarding the optimization of an integrated Mach-Zehnder interferometer with a
calibration waveguide refractometer based on silicon nitride rib waveguides with SU8 cladding. From modeling and
simulation studies a sensor structure has been designed which presents toleration to fabrication errors and input coupling
misalignments. The role of the chromium thin layer sections deposed over silicon nitride layer is analyzed in this work for
alleviating the misalignment coupling errors and for improvement of the measurement accuracy, respectively..
