A numerical analysis of a hexagonal PCF structure with four circular air hole rings around the core has been presented in this paper. By utilizing a full vectorial finite element method with perfectly matched layers, propagation properties such as birefringence, chromatic dispersion and confinement losses are numericaly evaluated for the proposed PCF structure. Specifically, birefringence of 2.018 × 10–2, nonlinear coefficients of 40.682 W−1 km−1, negative chromatic dispersion of − 47.72 ps/km.nm at 1.55 µm and − 21 to − 105 ps/km.nm at the telecommunication band of C-U have been reported.

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.

“…The high refractive index contrast between the core and cladding is strictly maintained to confine light in the core, which is the main mechanism for nonlinear effects. Silica PCFs are popular subjects of research because they exhibit numerous applications, such as optical communication (Kabir et al, 2020;Mohammadzadehasl & Noori, 2019), nonlinear optics (Park et al, 2020;Biswas et al, 2019), high power technology (Qi et al, 2018;Hasan et al, 2021), spectroscopy (Markin et al, 2017;Paul et al, 2020), and sensing applications such as gas sensing (Paul et al, 2018;Kaur & Singh, 2019) and chemical sensing (Podder et al, 2019;Eid et al, 2021) with its unique properties. Among them, supercontinuum (SC) generation (Lanh et al, 2019(Lanh et al, , 2020 has been widely studied, and outstanding results have been achieved in silica fiber.…”

We examine the possibility of improving the nonlinear properties of photonic crystal fibers (PCFs) with As2Se3 substrates by creating a difference in the diameters of the air holes of the rings around the core. With the new design, all-normal dispersion properties, small effective mode area, high nonlinear coefficient, and low confinement loss were achieved in the long-wavelength range of 2.0–7.0 µm. The highest nonlinear coefficient is 4414.918 W-1.km-1 at 4.5 µm for the lattice constant (Ʌ) of 3.0 µm and the filling factor (d/Ʌ) of 0.85, while the lowest loss is 1.823´10-21 dB/cm with Ʌ = 3.5 µm and d/Ʌ = 0.8. Based on the numerical simulation results, the characteristics of two optimal structures have been analyzed in detail to guide the application in supercontinuum generation.
