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)
We demonstrate a handover scheme for supporting high end-user mobility in a 60 GHz broadband picocellular Radio-over-Fiber network. The proposed scheme relies on a novel Moving Extended Cell (MEC) concept which is based on user-centric virtual groups of adjacent cells that transmit the same data content to the user. The MEC concept utilizes a mechanism for(More)
We demonstrate a novel scheme for 2R burst mode reception capable of operating error-free with 40 Gb/s variable length, asynchronous optical data packets that exhibit up to 9 dB packet-to-packet power variation. It consists of a single, hybrid integrated, SOA-based Mach-Zehnder Interferometer (SOA-MZI) with unequal splitting ratio couplers, configured to(More)
We report on the development of a flexible 2D optical fiber-based pressure sensing surface suitable for biomedical applications. The sensor comprises of highly-sensitive Fiber Bragg Grating elements embedded in a thin polymer sheet to form a 2x2 cm(2) sensing pad with a minimal thickness of 2.5mm, while it is easily expandable in order to be used as a(More)
We demonstrate an analytical model for calculating the saturation throughput performance of a medium transparent medium access control (MAC) protocol in 60 GHz radio-over-fiber (RoF) networks. The proposed model incorporates effectively the medium transparent MAC mechanism, assuming a finite number of terminals and ideal channel conditions. It takes into(More)
The 60 GHz millimeter-wave band remains the only unlicensed, high-capacity spectral zone which is however limited to Personal Area Networks due to its picocellular nature. Facilitating mm-wave communication onto Radio-over-Fiber infrastructures alleviates the picocellular range handicap while it offers multi-Gbps wireless connectivity. In light of the above(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)
Free space optical (FSO) communications links is a promising solution for the provision of high data rate point to point communications. The FSO links due to their huge bandwidth and license free spectrum provide a viable communication solution between Unmanned Aerial Vehicles (UAVs) and fixed Ground Stations (GS). It is of great importance to characterize(More)
We present a novel client-weighted mediumtransparent medium access control (CW-MT-MAC) protocol with enhanced fairness service delivery properties accompanied by a low-loss remote access unit (RAU) architecture for use in indoor, Gbps-capable, 60 GHz radio-over-fiber (RoF) wireless local area networks (WLANs). Our approach relies on incorporating a(More)
