The waveguide structure in this report is the two-dimensional air-hole type waveguide. It is shown that the inci- dent linear polarized lightwave is converted to the circular polarized lightwave. We also examine the photonic band gap for the chiral photonic crystal waveguide numerically. The band gaps of the right-circularly-polarized (RCP) and the left-circularly-polarized (LCP) waves depend on the chirality, and it is found that the band width of RCP is narrower than that of LCP. departmental bulletin paper 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2004-10 VoR application/pdf 宮崎大学工学部紀要 33 169 172 Memoirs of Faculty of Engineering, University of Miyazaki AA00732558 05404924 https://miyazaki-u.repo.nii.ac.jp/record/2994.1/files/KJ00002428240.pdf http://hdl.handle.net/10458/319 https://miyazaki-u.repo.nii.ac.jp/records/2994 jpn
