摘要

In this paper, a polarization-maintaining photonic crystal fiber (PCF) is numerically investigated for dispersion compensation. The core is formed by six inserted small air holes and the inner cladding consists of two lines of enlarged air holes adjacent to the core, which are both used to improve the birefringence. The proposed PCF can compensate for the dispersion and dispersion slope of a standard single mode fiber (SMF) at 1.55 mu m wavelength. The K value matches with that of SMF at 1.55 mu m wavelength very well. Moreover, the zero-dispersion wavelength (ZDW) is at 1.30 mu m wavelength, which also agrees with that of SMF. The designed PCF can realize an effective compensated dispersion range of -0.5 to + 0.1 psm/km from 1.32 mu m to over 1.7 mu m wavelength which covers the E + S + C + L + U bands. The confinement loss is ultra-low to 6 x 10(-4) dB/km at 1.55 wavelength. The influence of geometric parameters on the birefringence and the dispersion characteristic is investigated. The sensitivity of the fiber dispersion and the effective compensated dispersion to +/- 2% and +/- 5% variation in the optimum parameters is studied for practical fabrication.
