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/( is obtained in a 1.25 to 1.70 μm wavelength range i.e. 450 nm flat band along with low confinement(More)
Radioactive ion beams (RIB) have been produced on-line, using a gas-jet recoil transport coupled Electron Cyclotron Resonance (ECR) ion-source at the VECC-RIB facility. Radioactive atoms∕molecules carried through the gas-jet were stopped in a catcher placed inside the ECR plasma chamber. A skimmer has been used to remove bulk of the carrier gas at the ECR(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/( 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)
