Journal ArticleDOI
Electrical tuning of metal-insulator-metal metasurface with electro-optic polymer
Jiaqi Zhang,Yuji Kosugi,Akira Otomo,Ya-Lun Ho,Jean-Jacques Delaunay,Yoshiaki Nakano,Takuo Tanemura,Takuo Tanemura +7 more
TL;DR: In this article, the Fabry-Perot resonance of a metal-insulator-metal mode was used to trap the incident light inside a thin EO polymer layer to enhance the modulation efficiency.
Journal ArticleDOI
Active metasurface modulator with electro-optic polymer using bimodal plasmonic resonance.
TL;DR: A novel metasurface modulator based on electro-optic polymer that utilizes bimodal resonance inside a metallic subwavelength grating to increase the modulation efficiency and is potentially applicable to high-speed surface-normal modulators.
Journal ArticleDOI
Surface-normal electro-optic-polymer modulator with silicon subwavelength grating
TL;DR: Novel silicon-based surface-normal optical modulator using electro-optic (EO) polymer embedded inside a thin silicon subwavelength grating layer, which is used as both the interdigitated electrodes for effective poling of the EO polymer, and as high-Q resonant structure for the incident light to enable efficient modulation.
Proceedings ArticleDOI
Electro-optic polymer surface-normal modulator using silicon high-contrast grating resonator
Makoto Ogasawara,Yuji Kosugi,Jiaqi Zhang,Yuki Okamoto,Yoshio Mita,Akira Otomo,Yoshiaki Nakano,Takuo Tanemura +7 more
TL;DR: In this paper, a surface-normal optical modulator using electro-optic polymer embedded inside a 570-nmthick silicon high-contrast grating resonator is fabricated.
Proceedings ArticleDOI
Experimental Demonstration of Surface-Normal MIM Modulator with Electro-Optic Polymer
Jiaqi Zhang,Ya-Lun Ho,Yuji Kosugi,Jean-Jacques Delaunay,Takuo Tanemura,Akira Otomo,Yoshiaki Nakano +6 more
TL;DR: A novel metallic metasurface modulator with electro-optic (EO) polymer efficiently trap surface-normal incident light inside a 540-nm-thick EO polymer layer by using the resonance of a metal-insulator-metal mode.
