Abstract
A novel TE mode transmission waveguide polarizer has been designed based on SiO2/Si waveguide birefringence effect and based on the coupling mode theory. After numerical simulation by 3D FD-BPM method combined with transparent boundary condition, the typical polarizer can achieve a high extinction ratio over 50dB with the device length of 8mm at the wavelength of 1.55 μm. Without increasing the complexity of waveguide manufacturing, this structure can be directly used as a polarizer, and also can be integrated easily with other waveguide devices.
