“…Chromatic dispersion is one of the properties of optical ber that causes different wavelengths of light to propagate at different speeds and move along the optical ber [8]. In [9] and [10], PCF structures with low losses and dispersion have been proposed.…”

In this paper, a new structure of photonic crystal bers (PCFs) with large negative dispersion is presented in order to compensate the positive dispersion at a wavelength of 1.55 μm. The proposed PCF has square lattice structure. In the basic structure of the cladding, it consists of four square rings, so that each ring has a number of circular holes. In the nal proposed structure, the two inner rings of the cladding are reshaped relative to the two outer rings. The rst inner ring near the core has stellar shaped holes with gold nanoparticles in its center, and the second inner ring has circular holes with a smaller diameter than the two outer rings. The base material of this ber is silica. The use of stellar shaped holes with gold nanoparticles cores causes a large amount of negative dispersion, which compensates the positive dispersion. Simulation results show that the minimum dispersion is -4593 ps/(nm.km) at a wavelength of 1.55 μm which bring a signi cant improvement compared to other similar references.
