Characteristic Analysis of Polarization and Dispersion Properties of PANDA Fiber Using Finite Element Methods
نویسندگان
چکیده
One possible structure of a PANDA fiber is proposed and the effects of hydraulic stress on the propagation properties are studied in this work. The proposed PANDA fiber can withstand up to 1500MPa external hydraulic stress while maintaining the fundamental mode of propagation. Effects of hydraulic pressure on several propagation properties such as birefringence, beat length, effective index, dispersion, cutoff wavelength, and bandwidth are shown in this paper.

Meso-scale Modeling of Tension Analysis of Pure and Intra-ply Hybrid Woven Composites Using Finite Element Method
One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...
متن کاملDesign of low-dispersion fractal photonic crystal fiber
In this paper, a fractal photonic crystal fiber (F-PCF) based on the 1st iteration of Koch fractal configuration for optical communication systems is presented. Complex structure of fractal shape is build up through replication of a base shape. Nowadays, fractal shapes are used widely in antenna topics and its usage in PCF has not been investigated yet. The purpose of this research is to compar...
متن کاملHighly birefringent elliptical core photonic crystal fiber for terahertz application
We present a novel strategy for designing a highly birefringent photonic crystal fiber (PCF) with near zero flattened dispersion properties by applying elliptical air holes in the core area. The elliptical structure of the air holes in the porous-core region introduces asymmetry between x and y polarization modes, which consequently offers ultra-high birefringence. Also the compact geometry of ...
