摘要：
A novel kind of polarization splitter in dual-core elliptical holes hybrid photonic crystal fiber is proposed. Numerical results show that the splitter can reach small coupling length ratio of 0.5, for wavelength from 1.15 mu m to 1.9 mu m. At wavelength 1.55 mu m, the extinction ratio can achieve -64 dB and the 1.92-mm-long splitter is suggested to achieve extinction ratio better than -10 dB, a bandwidth of 150 nm. The fiber has small coupling length ratio, small coupling length and high extinction ratio and it is more suitable for fabricating polarization splitter. (c) 2012 Elsevier GmbH. All rights reserved.
