Polarization dispersion compensated Arrayed Waveguide Gratings Design Based on Silicon Nanowires

摘要

A simple method to design polarization dispersion compensated arrayed waveguide gratings based on silicon nanowires is proposed using angled star couplers with different diffraction orders for TE and TM polarizations. Polarization dispersion compensation for all channels is achieved by using a 380nm×220nm silicon waveguide with an upper-cladding of SU-8. The simulation results demonstrate the validity of the design.
