Abstract
In order to obtain ultra-smooth dispersion characteristics,a large mode area and a smaller limitation loss,starting from the Maxwell equations,taking into account the dispersion of pure quartz themselves,the mode field distribution of the photonic crystal fibers,effective index of fundamental modes and dispersion coefficient were calculated with the finite element method.With the fiber dispersion within ±1.0ps·km-1·nm-1,the mode area was larger than 40μm2,and the confinement loss was less than 0.2dB/km.The results show that the dispersion and mode field area of photonic crystal fibers can be controlled by adjusting the air hole diameter,the pitch size of the cladding air holes,and the media filling ratio.
