Abstract
A novel photonic crystal fiber polarization filter with Au-coated and liquid-filled air holes is designed in this paper. The coupling theory is introduced to explain the complete coupling and incomplete coupling. We can adjust the resonance point to the communication band by optimizing the parameters of the fiber structure. Numerical simulation results demonstrate that the resonance strength can reach 434dBcm−1 at the communication wavelength of 1.31μm in x-polarized direction. By filling liquid analyte can help adjust the resonance peak to the proper place. Furthermore, when the fiber length of L equals to 0.1cm, the crosstalk peak value can reach 353.74dB at the wavelength of 1.31μm, and the bandwidth of the crosstalk better than 20dB can reach 80nm when the length of the fiber L is 400μm. These characteristics make it a promising candidate for designing new types of polarization filter devices.
