In this paper, we numerically demonstrate a large negative dispersion with highly birefringent square lattice photonic crystal fiber (SLPCF) in the entire telecom wavelength bands. Finite element method with perfectly matched layer boundary condition is used to evaluate the modal properties of the fiber. Numerical results reveal that it is possible to(More)
This paper presents the proposal of a hybrid cladding photonic crystal fiber offering flat dispersion and low confinement operating in the Telecom bands. Simulation results reveal that near zero ultra flattened dispersion of 0 ± 1.20 ps/(nm.km) is obtained in a 1.25 to 1.70 μm wavelength range i.e. 450 nm flat band along with low confinement(More)
This paper presents a microstructure optical fiber based on an hexagonal structure for dispersion compensation in a wideband transmission system. According to simulation, negative dispersion coefficient of - 562 ps/(nm.km) and relative dispersion slope (RDS) close to that of single mode fiber (SMF) of about 0.0036 nm<sup>-1</sup> is obtained at 1550 nm(More)
Worldwide Interoperability for Microwave Access (WiMax), standardized asIEEE 802.16d is a popular technology for broadband wireless communication system. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology.OFDMreduces Inter-symbol Interference (ISI) and hence improves system performance (i.e., Bit Error Rate (BER)). To improve(More)
— It is now a banal truth that the environment is being subjected to plenty of environmental hazards. These are attributable to pollution that has completely overwhelmed the environment which in turn is also responsible for bringing about atrocious changes to the environment. The principle reason behind this change is increased carbon emission. Every day, a(More)
