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.; Kriezis E.E.; Beccherelli R.... more authors ... less 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.; Swillam, M. A.... more authors ... less 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 ... -
Near infrared plasmonic sensor based on Fano resonance
Sherif, S.M.; Shahada, L.; Zografopoulos, D.C.; Beccherelli, R.; Swillam M. ( SPIE , 2016 , Conference Paper)We introduce a compact plasmonic resonator that is capable of generating a Fano resonance in the transmission spectrum. The Fano resonance is observed with its unique lineshape. The proposed design is simple, compact, easy ...
