In this paper, two new square-lattice photonic crystal fibers (PCFs) are designed and
proposed. Both fibers have identical structures with five air-hole rings, yet the diameter of air …

In this study, a new photonic crystal fibre (PCF) structure is proposed which is suitable for
optical telecommunications. This PCF has some features including low-and ultra-flattened …

Photonic crystal fibers (PCFs) are highly suitable transmission media for wavelength-
division-multiplexing (WDM) systems, in which low and ultra-flattened dispersion of PCFs is …

A new type ultraflattened dispersion square-lattice photonic crystal fiber with two different air-
hole diameters in cladding region is proposed and the dispersion is investigated using a …

In this article, an octagonal photonic crystal fiber is proposed, in which the core region and
four air holes in the inner ring have a refractive index of 1.43. Compared with the hexagonal …

In this study we propose a new photonic crystal fiber (PCF) design that simultaneously offers
broadband single-mode operation, high birefringence, and large normal dispersion in the …

A new design of large mode area (LMA) circular lattice photonic crystal fiber (CL-PCF) is
proposed and numerically investigated. The cladding is formed by six rings of air holes …

This paper presents four rings square, circular, and hexagonal photonic crystal fiber (PCF)
geometry for analyzing different optical properties in a wavelength ranging from 800 nm to …

Two photonic crystal fiber structures with quad-core have been investigated in this paper.
Both the structures are geometrically similar but have different background materials. Both …

In this paper, confinement loss in hexagonal lattice photonic crystal fibers (PCFs) has been
investigated. Using finite difference frequency domain (FDFD) method with perfectly …
