Abstract: A novel photonic crystal fiber featured by concentric cores is proposed to induce dispersion controllability by photosensitivity. Chromatic dispersion can be changed from -1827 to 72ps/nm/km with refractive index modulation of 4 × 10-4 produced in Ge-doped regions in the fiber. Effective mode area of inner mode is as small as 6.4 μm2. The proposed fiber enables to achieve quasi-phase-matched nonlinear parametric interaction in a single piece of photonic crystal fiber, by periodically alternating dispersion and compensating for phase mismatching caused by the dispersion. © 2007 Optical Society of America.
