This research analyzes polarization aberrations in a modified Mach-Zehnder interferometer to improve nulling depth for mid-infrared exoplanet detection. By modeling the impact of optical coatings and geometry on polarization states, the study provides optimization strategies to overcome the critical 10⁻⁶ contrast limitation. These advancements are essential for the high-precision detection of temperate rocky exoplanets using next-generation nulling interferometry.
