Design of ultra-short polarization convertor with enhanced birefringence by photonic crystals
We report that the birefringence of the polarization convertor in silicon-on-Insulator channel waveguide could be enlarged using photonic crystals. The photonic crystals consist of etched air holes shifted to the center of the waveguide. The polarization rotation due to the asymmetric modes in the s...
