Extinction ratio and wavelength flatness for imbalanced Mach-Zehnder interferometer in silicon-on-insulator

ABSTRACT The imbalanced Mach–Zehnder interferometer typically uses two multimode interferences individually connected with different path length for interferometric applications. When the optical loss difference between two phase arms is significant, the new splitting scheme using Mach–Zehnder based...
