Paper Abstract

The polarization control(PC), as one of the important issues in photonic information technologies, has attracted great attention. In this paper, we proposed an efficient and compact polarization converter on silicon-on-insulator (SOI) platform based on asymmetrical direction couplers (ADCs). The ADCs consists of two parallel fully etched straight waveguides with different sizes in both width and height. This polarization converter can realize direct conversion between the TE0 mode and the TM0 mode with high conversion efficiency. Numerical simulations show that the present PC has a good fabrication tolerance for the variation of the waveguide width and height with high polarization conversion efficiency up to 82%.
