All-optical switch and logic gates based on all-dielectric hybrid silicon-Ge2Sb2Te5 metamaterials
Zhaojian Zhang, Junbo Yang, Wei Bai +6
We numerically propose an all-dielectric hybrid metamaterial (MM) to realize all-optical switch and logic gates in shortwave infrared (SWIR) band. Such MM consists of one silicon r…
Chipscale plasmonic modulators and switches based on metal-insulator-metal waveguides with Ge2Sb2Te5
Zhaojian Zhang, Junbo Yang, Wei Bai +7
We introduce phase-change material Ge2Sb2Te5 (GST) into metal-insulator-metal (MIM) waveguide systems to realize chipscale plasmonic modulators and switches in the telecommunicatio…
Actively tunable terahertz electromagnetically induced transparency analogue based on vanadium-oxide-assisted metamaterials
Zhaojian Zhang, Junbo Yang, Yunxin Han +6
Recently, phase-change materials (PCMs) have drawn more attention due to the dynamically tunable optical properties. Here, we investigate the active control of electromagnetically…
A plasmonic ellipse resonator possessing hybrid modes for ultracompact chipscale application
Zhaojian Zhang, Junbo Yang, Heng Xu +7
We propose a plasmonic ellipse resonator possessing hybrid modes based on metal-insulator-metal (MIM) waveguide system. Specially, this nanocavity has hybrid characteristic of rect…
