摘要：
A passive TE mode phase shifter-based compact structure of optical Mach-Zehnder interferometer (MZI) using silicon-on-insulator (SOI) platform is demonstrated by using BPM simulations. Insertion loss was found, that is 9 dB for 3 m width, 16 dB for 1.55 m wavelength, 0.9 dB for 2000 m path length (arms), and 15 dB for 0.0055 index differences between the core and the cladding of SOI of the designed device. The Mach-Zehnder interferometer attains good phase shifts by changing the path lengths (arm) with TE mode polarisation.
