    • Amplitude modulation in infrared metamaterial absorbers based on electro-optically tunable conducting oxides 

      Zografopoulos D.C.; Sinatkas G.; Lotfi E.; Shahada L.A.; Swillam M.A.; ... more authors ( Springer Verlag , 2018 , Article)
      A class of electro-optically tunable metamaterial absorbers is designed and theoretically investigated in the infrared regime towards realizing free-space amplitude modulators. The spacer between a subwavelength metallic ...

    • Hybrid plamonic conductor-gap-silicon microring-on-disks electro-optic modulator 

      Fouad, N. H.; Zaki, A. O.; Zografopoulos, D. C.; Shahada, L. A.; Beccherelli, R.; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      In this work, we propose a novel design of a double microring-on-disk electro-optic modulator based on hybrid plasmonic conductor-gap-silicon platform utilizing the electromagnetic induced transparency response. The modulator ...

    • Integrated plasmonic refractometric sensor using Fano resonance 

      Sherif, S M; Zografopoulos, D C; Shahada, L A; Beccherelli, R; Swillam, M ( Institute of Physics Publishing , 2017 , Article)
      We propose a plasmonic refractometric sensor that is based on Fano resonances excited in a resonant rectangular cavity coupled to a metal-insulator-metal bus waveguide. The properties of the resonances are controlled by ...

    • Metathesis ring opening polymerization of 5,6-dimethylenebicyclo[2.2.1]hept-2-ene 

      Shahada, L. A.; James Feast, W. ( John Wiley & Sons, Ltd , 1992 , Article)
      5,6-Dimethylenebicyclo[2.2.1]hept-2-ene (I) polymerizes in the presence of the two-component ring opening metathesis polymerization (ROMP) initiators WCl6/(CH3)4Sn and MoCl5/(CH3)4Sn. The product polymers were insoluble ...

    • On Chip Optical Modulator using Epsilon-Near-Zero Hybrid Plasmonic Platform 

      Swillam M.A.; Zaki A.O.; Kirah K.; Shahada L.A. ( Nature Publishing Group , 2019 , Article)
      In this work, we propose a micro-scale modulator architecture with compact size, low insertion loss, high extinction ratio, and low energy/bit while being compatible with the silicon-on-insulator (SOI) platform. This is ...

    • Sub-Femtojoule Hybrid Plasmonic Optical Modulator 

      Sherif S.M.; Elsayed M.; Shahada L.A.; Swillam M.A. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)
      A highly compact optical modulator is proposed and analyzed. The modulator is based on the hybrid plasmonic waveguide platform. The structure of the modulator is built from silicon, silver, and electro-optical polymer ...

    • Vertical silicon nanowire-based racetrack resonator optical sensor 

      Sherif S.M.; Elsayed M.Y.; Shahada L.A.; Swillam M.A. ( Springer Verlag , 2019 , Article)
      We propose a highly sensitive optical sensor which is built from silicon nanowires. The silicon nanowires are arranged to form a ring resonator. The silicon nanowires cladding and voids are filled with the analyte. The ...
