摘要:
摘要： An ultra-compact polarization splitter based on asymmetric metal/multi-insulator directional coupler is proposed and investigated analytically and numerically. A large modal birefringence of >;0.69 is estimated, enabling a clean polarization selective directional coupling within 5.6. The insertion loss of and the splitting and extinction ratios of <;-0.32 are predicted. Modified coupled-mode equations for a coupled lossy waveguide system are also presented. 其他題名： LPT 出版者： IEEE 出版日期： 2012-03-15 出處： IEEE Photonics Technology Letters, 2012-03, Vol.24 (6), p.458-460 資源來源： IEEE Electronic Library (IEL) 識別號： ISSN: 1041-1135 識別號： EISSN: 1941-0174 識別號： DOI: 10.1109/LPT.2011.2181352 識別號： CODEN: IPTLEL
