چکیده انگلیسی
A broadband core shift photonic crystal fiber (PCF) polarization filter based on surface plasmon resonance is proposed in this paper. The fiber is consisted of an asymmetric hexagonal lattice of holes in which a small air hole is coated with gold film and another one large air hole destroyed the structure around the core. The loss of y-polarized core mode is 2232.61â¯dB/cm at the communication wavelength of 1.55â¯Î¼m, however, the loss of x-polarized core mode is very weak. When the PCF length is 300â¯Î¼m, the bandwidth of exceeding 420â¯nm with extinction ratio better than â20â¯dB is achieved. To our best knowledge, the bandwidth is the widest. As a consequence, this special fiber filter has a wider range of applications.
