Journal of Lightwave Technology, 2013Co-Authors: Chigo M. Okonkwo, D Visani, Eduward Tangdiongga, Ton KoonenAbstract:This paper presents a point-to-multipoint (P2MP) in-home optical network infrastructure based on 1-mm Core Diameter plastic optical fiber (POF). By employing passive POF splitters, converged broadband wired and wireless service transmission over a P2MP POF infrastructure is demonstrated. A gross 2.2 Gb/s fractional discrete multitone (DMT) and a 528-MHz ultra wideband (UWB) wireless signal distribution simultaneously to four end-users are successfully achieved with BER <; 10-3 and EVM <; 15.5% , respectively. Up to 50 m transmission distance is achieved using off-the-shelf optical components. This feasibility study on all-optical P2MP infrastructures presents a promising low-cost solution for high-speed in-home broadband communication.

Greiss, Eduward Tangdiongga, Olaf ZiemannAbstract:Recent activity to achieve multi-gigabit transmission over 1 mm Core Diameter graded-index and step-index plastic optical fibers for distances up to 50 meters is reported in this paper. By employing a simple intensity-modulated direct-detection system with pulse amplitude or digital multi-tone modulation techniques, low-cost transceivers and easy to install large-Core POFs, it is demonstrated that multi-gigabit transmission up to 10 Gbit/s over 1-mm Core Diameter POF infrastructure is feasible. The results presented in this paper were obtained in the EU FP7 POF-PLUS project, which focused on applications in different scenarios, such as in next-generation in-building residential networks and in datacom applications.

molecular dynamics study of defect and dislocation behaviors during tensile deformation of copper silver Core shell nanowires with varying Core Diameter and shell thickness
Journal of Nanoparticle Research, 2018Co-Authors: Jit SarkarAbstract:Core-shell type nanostructures have drawn much attention among material researchers as they exhibit exceptional properties due to their unique structure. Among different Core-shell nanostructures, copper-silver Core-shell nanostructures are widely investigated in recent days for exhibiting different unique properties like very high mechanical strength. Molecular dynamics simulations were carried out to investigate the underlying deformation mechanism during tensile testing of copper-silver Core-shell nanowires with varying Core Diameter and shell thickness. The Wigner-Seitz defect analysis was used to calculate the total number of point defects like vacancies and interstitials during the entire deformation process. The type, number, and total length of dislocation segments were thoroughly investigated throughout the different stages of deformation. The effects of varying Core Diameter and shell thickness on the defect and dislocation configurations were also studied. Thus, this study helps us to understand the underlying mechanisms or factors that contribute to the ultra-high strength and mechanical properties of Cu-Ag Core-shell nanowires with varying Core Diameter and shell thickness.
