“…In fact, if a ber has a negative dispersion in a wavelength range; it can compensate positive dispersion in this wavelength range. To minimize losses and reduce costs, the dispersion of ber should be as small as possible [8].…”

“…Dispersion in a ber occurs when an optical pulse moves through an optical ber and its power changes over time, resulting in the pulse propagating over a wider period of time. 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.…”

Large negative dispersion in photonic crystal fiber by applying gold nanoparticles in square cladding

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.

A theoretical and numerical investigation of transient dynamics of stimulated Raman scattering (SRS) inside gas-filled hollow-core photonic crystal fibers (HCPCFs) is reported here. A clear link between the transient dynamics and the coherent memory of the SRS interaction is demonstrated. In addition, the role of pulse width, pump power, fiber length, and gaseous medium in the transient dynamics of SRS in HCPCFs is discussed. It is shown that the coherent memory can serve as a convenient parameter to control the SRS propagation regime.
