Numerical demonstration of hexagonal-shaped dual-core-based photonic crystal fiber for a wide telecommunication window
This paper proposes a novel hexagonal-shaped dual-core photonic crystal fiber (HX-PCF) for a wide telecom window. We test different optical parameters including birefringence (Bi), power fraction (η′), effective area (Aeff), numerical aperture (NA), nonlinear coefficient (γ), v-parameter, chromatic dispersion (β2), transmittance) (Tx), and relative sensitivity (Rs) and loss profiles including effective material loss, confinement loss (αc), scattering loss (αsc), and bending loss (αbl) compared with the most recent models. In addition, the finite element method is employed on wavelength-division multiplexing with 310,534 mesh elements over a wide telecom window wavelength range of 1500–3000 nm and porosity of 30–60%. The proposed HX-PCF displays outstanding performance for these parameters. The optimal key performance indicator profiles are 2.2 × 10−3, 99.79%, 1.69 × 10−11 m2, 0.99, 0.203 m−1, 10−9 dB/m, 18.5 × 10−3 dB/m, 10−8 dB/m, 9.1 × 1010 W−1 km−1, 185 ps/(nm.km), −240 dB, and 41.75%, respectively, for the corresponding optical parameters of Bi, η′, Aeff, NA, αEML, αc, αsc, αbl, γ,β2, Tx, and Rs. This fiber is more promising than any previous model, based on ultra-flattened dispersion, high nonlinearity, high NA, transmittance, and relative sensing, along with very low loss profiles. Moreover, it is shown to be a good candidate for telecommunication, optoelectronics, four-wave mixing, fiber loop mirroring, and other high-speed transmission media.
