【 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 $\mu$m width, 16 dB for 1.55 $\mu$m wavelength, 0.9 dB for 2000 $\mu$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.
