(1)Istituto per la Microelettronica e Microsistemi (Italy) , (2)The American University in Cairo (Egypt) , (3)Qatar University (Qatar) By breaking the diffraction limit, plasmonics enable the miniaturization of integrated optical signal processing units in a platform compatible with traditional CMOS technology. In such architectures, modulators and switches are essential elements for fast and low-power optical signal processing. This work reviews the state-of-the-art on electro-optical plasmonic integrated components, comprising different propagation length scales and tuning mechanisms. Among these, particular attention is paid to the Pockels effect in non-linear polymers and the electro-optical switching of nematic liquid crystalline materials.
17:00 Invited talk : Hybrid Plasmonics for Integrated Optics and Sensing Applications
University of Toronto (Canada) Hybrid plasmonic waveguides and structures provide a new platform for design and fabrication of integrated optical devices and sensors. By merging the silicon photonics with plasmonics, the hybrid plasmonic promises a new platform which enables the design of extremely compact and efficient integrated devices with notably reduced real-state on the chip. Moreover, the uses of hybrid plasmonic technology in design of sensors will at least double the amount of date gathered during a single sensing event.
17:20 : Brewster mode or how to optically monitor the doping concentration in highly doped semiconductor layers

(1)University of Montpellier (France) , (2)Paris Sud University (France) We propose a new experimental technique to accurately measure the plasma frequency of metallic layers and notably doped semiconductors. The technique is based on reflectance measurements evidencing a resonant dip near the plasma frequency. Based on Fresnel coefficients in the case of transverse electromagnetic waves, we propose that this resonance is due to the excitation of a leaky electromagnetic mode, the Brewster mode, propagating in the metallic layer deposited on a dielectric material.
