.Effects of quasi-periodicity on defect modes of photonic crystals[J].Optoelectronics Letters,2006,2(4):292-295 Effects of quasi-periodicity on defect modes of photonic crystals SHEN Xiao-ming CHEN Xian-feng JIANG Mei-ping CHAO Xiao-gang SHI Du-fang [1]Department of Information Science, Jiangsu Polytechnic University, Changzhou 273076, China [2]Depart of Physics, Huazhong University of Science and Technology, Wuhan 430074, China Abstract:       In this letter, the effects of Bragg-mirror quasi-periodicity on the shifts and quality factor in defect modes of photonic crystals are studied by using the transfer matrix method. Furthermore the influence of the quasi-periodicity on electric field enhancement effect inside the defect layer is studied,which is similar to that on the quality factor.
