摘      要：We propose a novel optical polarizer based on an asymmetric dual-core photonic crystal fiber(PCF) with triangular lattice *** fiber is designed as that the effective indices of modes in the two cores are matched at one polarized state but mismatched at another polarized *** a result,one of the polarization states is coupled to the other core and transferred into a high-order *** transmission properties of the polarizer are investigated by the semi-vectorial beam propagation method(SV-BPM).Numerical results demonstrate that a device length of 11.3 mm shows extinction ratio as low as-20 dB with bandwidth as great as 80 nm ranging from 1.51 mm to 1.59 mm.
