This article proposed an ultra-large negative dispersion defected octagonal PCF (OPCF) to
address the issue of dispersion in fiber communication. Using the Finite Element Method …

In this paper, a hexagonal shape photonic crystal fiber (H-PCF) has been proposed using
only circular air holes for the application of air pollution monitoring. A Perfectly matched …

A single-mode defected core hexagonal photonic crystal fiber (H-PCF) is presented for the
wide-band dispersion compensation at the wavelength interval 1350 to 1600 nm over the …

We numerically demonstrate an improved photonic crystal fiber using octagonal structure
due to its achievement in ultra-high negative dispersion value and large nonlinearity …

This paper discusses a new defected core octagonal photonic crystal fiber (DC-OPCF) with
six elliptical form air holes in the core area to improve the dispersion and nonlinear …
