The plane wave expansion method and the finite-difference time-domain method are employed to calculate photonic bandgap and to simulate wave propagation, respectively. Firstly, Three line-defect waveguides which can guide only the transverse electric (TE) wave, only the transverse magnetic (TM) wave, and both the TE and TM waves are designed in a compound-type lattice with a complete photonic bandgap. Secondly, an asymmetric Y-junction polarization splitter is designed based on the three line-defect waveguides. Transmission efficiencies of the polarization splitter can be improved by modifying the radius of the air holes. According to simulation results, transmission efficiencies larger than 85% and 95% can be obtained for TM and TE waves, respectively. Chen, Rei-Shin 陳瑞鑫 2013 學位論文 ; thesis 59 zh-TW
