—We demonstrate a Moving Extended Cell concept that provides seamless communication with high end-user mobility in broadband 60 GHz Radio-over-Fiber networks. Mathematical and simulation-based performance analysis are presented, showing that this technique can guarantee seamless connectivity irrespective of the overlapping area between adjacent cells(More)
—Digital optical logic circuits capable of performing bit-wise signal processing are critical building blocks for the realization of future high-speed packet-switched networks. In this paper, we present recent advances in all-optical processing circuits and examine the potential of their integration into a system environment. On this concept, we demonstrate(More)
With metal stripes being intrinsic components of plasmonic waveguides, plasmonics provides a "naturally" energy-efficient platform for merging broadband optical links with intelligent electronic processing, instigating a great promise for low-power and small-footprint active functional circuitry. The first active Dielectric-Loaded Surface Plasmon Polariton(More)
As the interest for Silicon-On-Insulator (SOI) waveguides is increasing, it would be valuable to have an explicit simulation method to provide a framework for quick and low cost analysis of the optical effects in silicon waveguides. This paper focuses on modeling the inherent optical properties of silicon waveguides using the finite-difference-time-domain(More)
Finite Element Method constitutes one of the most powerful numerical methods when there is need for approximate solutions of a problem. In this work an application with a user-friendly graphical interface, developed in Matlab, is presented which facilitates the calculation and graphical presentation of the propagation constants and modes of various types of(More)
