In order to obtain symmetrical high birefringence photonic crystal fiber filled with Au. The fundamental mode of the fiber core, dispersion and loss characteristics of plasma polaritons of metal surface were analyzed by means of finite element method. The resonance positions and the resonance strength between fundamental mode and plasma polaritons could be well adjusted by changing the distances between the cladding air holes, the diameters of air holes around the core and the diameter of metal wire. By optimizing the parameters of fiber structure, a polarization filter at the communication band was designed. After numerical aperture of air hole was determined, fundamental mode loss in x-position could reach 473dB/cm and fundamental mode loss of y-position was almost not affected by surface plasma polariton (SPP) mode at the wavelength of 1.55m. The results show that compared with ordinary single-polarization and single-mode photonic crystal fibers, the polarized light in one direction can be filtered out selectively by adjusting the wire diameter and achieve filtering effect in the communication band. It is meaningful for the development of polarization filters in the communication band.

Abstract: In order to obtain symmetrical high birefringence photonic crystal fiber filled with Au. The fundamental mode of the fiber core, dispersion and loss characteristics of plasma polaritons of metal surface were analyzed by means of finite element method. The resonance positions and the resonance strength between fundamental mode and plasma polaritons could be well adjusted by changing the distances between the cladding air holes, the diameters of air holes around the core and the diameter of metal wire. By optimizing the parameters of fiber structure, a polarization filter at the communication band was designed. After numerical aperture of air hole was determined, fundamental mode loss in x-position could reach 473dB/cm and fundamental mode loss of y-position was almost not affected by surface plasma polariton (SPP) mode at the wavelength of 1.55m. The results show that compared with ordinary single-polarization and single-mode photonic crystal fibers, the polarized light in one direction can be filtered out selectively by adjusting the wire diameter and achieve filtering effect in the communication band. It is meaningful for the development of polarization filters in the communication band.
