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…
On-chip broadband plasmon-induced transparency based on plasmonic metal-insulator-metal waveguides
Zhaojian Zhang, Junbo Yang, Siyu Xu +6
As an analogue of electromagnetically induced transparency (EIT), plasmon-induced transparency (PIT) has been realized both in plasmonic metamaterial and waveguide structures. Via…
Active control of broadband plasmon-induced transparency in terahertz hybrid metal-graphene metamaterial
Zhaojian Zhang, Junbo Yang, Xin He +5
A hybrid metal-graphene metamaterial (MM) is reported to achieve the active control of the broadband plasmon-induced transparency (PIT) in THz region. The unit cell consists of one…
