Reduction of Effective Material Loss (EML) Using Decagonal Photonic Crystal Fiber (D-PCF) for Communication Applications in the Terahertz Wave Pulse

Abstract

We present an excellent design of five layers of decagonal shape in the cladding area and two elliptical shapes of core area based photonic crystal fiber (PCF) for many types of communiqué arenas in the THz wave pulse in this study. The Finite Element Method with perfectly matched layers used the optical parameters of our proposed D-PCF structure numerically to design and analyze. Therefore, D-PCF shows a low effective material loss of 0.0079 cm−1, an increase in effective area of 3.49 × 10–8 m2, a core power fraction of 85%, a low confinement and scattering loss, of 3.35 × 10–16 and 1.27 × 10–10 dB/km respectively at 1 THz of frequency. After analyses all the graphical results, our proposed D-PCF will be highly suitable for communiqué parts in the THz regions
