A novel design of polarization filter based on photonic crystal fiber (PCF) is proposed in this paper. With the introduce of a gold-coated air hole, the loss of y polarized mode is 2138.34 dB/cm while the loss is very low in x polarization at the wavelength of 1.31 μm. The significant loss in y polarization makes this PCF a good candidate for developing a polarization filter with high performance...
A novel design of a polarization filter based on photonic crystal fiber (PCF) is proposed in this paper. With the introduction of a gold-coated air hole, the resonance strength is much stronger in y-polarized direction than in x-polarized direction at some particular wavelengths, which is due to the metal surface plasmon effects. At the wavelength of 1.31 μm, the loss of y-polarized mode is 2138.34 dB/cm...
A broadband single-polarization photonic crystal fiber polarized filter based on surface plasmon resonance is proposed based on finite element method. Numerical simulations show the confinement loss of y-PCM (y-polarized core mode) is much higher than that of x-PCM (x-polarized core mode) in the wavelength range 1.20–1.63 μm. The confinement loss of y-polarized mode is 45,240 and 10,200 dB/m at the...
