.Research on the stability of nearly zero flattened dispersion of photonic crystal fibers[J].Optoelectronics Letters,2008,4(2):117-120 Research on the stability of nearly zero flattened dispersion of photonic crystal fibers HU Jie WANG Jian Key Laboratory of Luminescence and Optical Information, Ministry of Education, Institute of Optical Information, School of Science, Beijing Jiaotong University, Beijing 100044, China Abstract:       To analyze the stability of nearly zero flattened dispersion,the dispersion deviations for three kinds of PCFs arc calculated when the hole diamcters deviate from their designed values.Numerical resuIts show that around the wavelength of 1.55μm,the dispersion deviations of both the PCF with three-fold symmetry core and the PCF with hexagonal lattice are much less than that of the PCF with different hole diameters in different rings.Therefore.the stabilities of nearly zero flattened dispersion of the first two kinds of PCFs are much better than that of the last one.Considering the confinement loss.the PCF with three-fold symmetry core is preferabk to practical USe.
