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)
The field of data communications and short-range interconnects in computing and High Performance Data Centers (HPCs) and Computing Systems has been up to date almost exclusively dominated by electronics, which have formed the main technological solution for the interconnection of many core/board/rack modules. In FP7-PLATON project we are investigating novel(More)

We present a hybrid integrated photonic circuit on a silicon-on-insulator substrate that performs ultra high-speed all-optical wavelength conversion. The chip incorporates a 1.25 mm non-linear SOA mounted on the SOI board using gold-tin bumps as small as 14 μm. Τhe device performs chirp filtering and signal polarity inversion with two multi-mode(More)
We demonstrate an optically controlled 2x2 Crossbar switch suitable for all-optical switching architectures. The switch is based on an Ultrafast Nonlinear Interferometer (UNI) configuration and uses 80 centimeters of highly nonlinear Bismuth Oxide fiber. Error-free operation is demonstrated with 10 and 40 Gb/s input signals, with power penalties in its BAR(More)
One of the key issues in Central Processing Unit (CPU) chips is the “Memory Wall” problem, where the clock frequency of RAM circuits cannot keep up in pace with the clock of the multiple cores. The current approach by chip architects to tackle this obstacle is to increase constantly the size of the cache memories on the dye in order to prevent(More)
We demonstrate Wavelength Division Multiplexed (WDM)-enabled transmission of 480Gb/s aggregate data traffic (12x40Gb/s) as well as high-quality 1x2 thermo-optic tuning in Dielectric-Loaded Surface Plasmon Polariton Waveguides (DLSPPWs). The WDM transmission characteristics have been verified through BER measurements by exploiting the heterointegration of a(More)
The vast amount of new data being generated is outpacing the development of infrastructures and continues to grow at much higher rates than MooreâĂŹs law, a problem that is commonly referred to as the âĂIJdata deluge problemâĂİ. This brings current computational machines in the struggle to exceed Exascale processing(More)
