摘要：With a fully vectorial effective index method,the total dispersion
   coefficient of photonic crystal fiber is calculated,and it is deeply
   analyzed that how the total dispersion coefficient is affected by the
   structural parameters.It is found that the dispersion coefficient has
   two-extreme characteristics with the changes of structural parameters.1)
   When Lambda is unchanged,with the reduction of d/Lambda,the
   zero-dispersion wavelength(ZDW) moves to the long wavelength.After
   reaching the maximum ZDW(MZDW),instead,the ZDW moves to the short
   wavelength.For example,when Lambda=2.3 mum,the MZDW is about 1728.9
   nm,as d/Lambda=0.24,and the smaller Lambda has the longer MZDW than the
   larger.2) When d/Lambda is unchanged,with the reduction of Lambda,the
   ZDW moves to the short wavelength.After reaching the minimum
   ZDW(M-ZDW),the ZDW moves to the long wavelength.For example,when
   d/Lambda=0.9,the M-ZDW is about 564.29 nm,as Lambda=0.6 mum,and the
   larger d/Lambda has the shorter M-ZDW than the smaller.These discoveries
   could be used to optimize design of the special photonic crystal fiber.
