Abstract

To restrain the pulse broadening in the communication system, a new type of dual-concentric-core photonic crystal fiber (DCCPCF) composed of single silica material is put forward based on the theory of dispersion compensation. The dispersion value of fundamental mode can achieve up to -6000ps/(nm · km) at 1.55μm. Analysis indicates that the inner core fundamental and outer core defect mode with phase-matching wavelength (λ_p) as a critical state will propagate forward alternatively between the inner and outer core region, and the effective indices intensely appears fluctuations due to modes coupling at phase-matching wavelength. By analyzing the perturbation of dispersion with two structure parameters d₁, d₂ changing, the instruction for actual fabrication at a certain extent is provided.
