Abstract :
The dispersion properties of large-hole photonic crystal fibers (PCFs) are tailored by changing the diameter of the air-holes belonging to the first three rings, in order to obtain fibers with a small effective area and low dispersion values in a wide wavelength range around 1550 nm. Highly nonlinear triangular PCFs with effective area of a few square micrometers, flattened dispersion curve, and zero-dispersion wavelength around 1500 nm have been designed.
