“…An important characteristic of this graph is that, it shows a tuneable zero chromatic dispersion between 0.9 and 1.1 μm for all the values of the Λ agreeing with refs. [35] and [36]. Negative dispersion is also obtained between 0.8-1.0 μm.…”

“…The result shows an increase in the confinement loss as the wavelength increases with the value of 1.55 μm being 2.767 × 10 −5 dB m −1 at Λ = 2.3 μm which is better than [10,[33][34][35].…”

“…The birefringence is a property that is very important in sensing applications [43] where light is essential to provide a maintained linear polarisation and it is useful in switching applications. The graph indicates a birefringence of the order of 10 −3 dB m −1 which corresponds to [13,35,[44][45][46]. Figure 4, shows a relationship between the birefringence and the wavelength and as such, as wavelength increases birefringence increase.…”

“…However, the dispersion is not tuneable and the air holes in the core are complex. Rahul [35] proposed a birefringence of 10 −3 , a tuneable dispersion at 0.8 to 0.95 μm and a confinement loss of 39.22 dB m −1 however, it has elliptical holes which would make fabrication a challenge. A double zero tuneable dispersion was proposed by ref.…”

A four-ring microstructure photonic crystal fibre with a descending air hole ring cladding is presented. Numerical analysis of the structure is done using full vectorial finite element method with perfectly matched layer (PML) boundary condition. It is demonstrated that it is possible to achieve at 1.55 µm confinement loss of 2.767 × 10−5 dB/m, birefringence of 0.00346 and a nonlinear co-efficient of 41.77 km−1 W−1. Also, chromatic dispersion realised suggests a tuneable zero dispersion at 0.9–1.1 µm wavelength range.

“…The proposed PCF structures have very high birefringence to separate the two polarization modes. This kind of PCF structure is very useful for polarizing maintaining devices, dispersion compensating devices, nonlinear applications, and sensing applications [16]. Properly engineering the position, dimension, and number of air holes, PCFs grant some attractive properties like ultra-flattened chromatic dispersion, very high nonlinearity, lofty sloping negative dispersion, slight confinement loss, small and huge effective mode area (A eff ), and high birefringence [17,18].…”

A unique hexagonal lattice structure of silica-based solid core photonic crystal fiber (PCF) surrounded by array of air holes is proposed. The cladding portion of the structure consists of five rings where core is made up of 11 small rings filled with methanol. Three different-shaped structures are used to analyze the effect on PCF parameters where the first structure uses circular air holes in cladding and core, the second structure consists of circular air holes in cladding and elliptical air holes in core, and the last structure was designed by using elliptical air holes in both cladding and core. Optical properties birefringence, confinement loss, and negative dispersion have been found theoretically and compared. A novel and relatively simple approach depicts the results that attain high birefringence, low confinement loss, and negative dispersion. It is found that the presence of elliptic air holes instead of circular air holes in the core region and the cladding brings higher birefringence, low confinement loss, and highly negative dispersion.
