“…When the wavelength decreases, the normalized frequency V increases, where its normalized cut-off frequency is 2.405. Unlike traditional optical fibers, the core of PCF is composed of a defect that periodically destroys the cladding structure [ 32 ]. Therefore, for PCF, the normalized frequency V is defined as follows:

where n eff and n FSM represent the effective RI of the core fundamental mode and the cladding fundamental space-filling mode (FSM), respectively, and Λ is the spacing of adjacent air holes.…”

Due to their flexible structure and excellent optical characteristics hollow-core photonic crystal fibers (HC-PCFs) are used in many fields, such as active optical devices, communications, and optical fiber sensing. In this paper, to analyze the characteristics of HC-PCFs, we carried out finite element analysis and analyzed the design for the band gap cladding structure of HC-PCFs. First, the characteristics of HC19-1550 and HC-1550-02 in the C-band were simulated. Subsequently, the structural optimization of the seven-cell HC-1550-02 and variations in characteristics of the optimized HC-1550-02 in the wavelength range 1250–1850 nm were investigated. The simulation results revealed that the optimal number of cladding layers is eight, the optimal core radius is 1.8 times the spacing of adjacent air holes, and the optimal-relative thickness of the core quartz-ring is 2.0. In addition, the low confinement loss bandwidth of the optimized structure is 225 nm. Under the transmission bandwidth of the optimized structure, the core optical power is above 98%, the confinement loss is below 9.0 × 10−3 dB/m, the variation range of the effective mode field area does not exceed 10 μm2, and the relative sensitivity is above 0.9570. The designed sensor exhibits an ultra-high relative sensitivity and almost zero confinement loss, making it highly suitable for high-sensitivity gas or liquid sensing.

The multicore fibre (MCF) is an effective and auspicious technology to overawe the limitation of the single-mode fibre. One of the important applications of MCF is power over fibre. In this paper, we have been designed eight different hexagonal structures by using 6, 7, 8, 9, 10, 11, 12 and 13 cores MCF. Those designs are categorized as even core multicore fibre (ECMCF) for 6, 8, 10 and 12 cores and odd core multicore fibre (OCMCF) for 7, 9, 11 and 13 number of cores. We also studied the impact analysis of odd or even number of the cores. The proposed designs having 140 µm diameter, large effective area of 1256 µ2m and two pitches d1=20 µm and d2=10 µm. The comparative analysis has been done by core multiplicity factor, electric field, coupled power, cross overpower parameter calculated for 10,000 samples. The hexagonal core shape MCF shows better performance if the number of the core in even number.
