Tunable THz generation and enhanced nonlinear effects with active and passive graphene hyperbolic metamaterials
Boyuan Jin, Tianjing Guo, Liang Zhu +2
The active and nonlinear graphene properties are limited due to weak light matter interaction between the ultrathin graphene and the incident light. In this work, we present enhanc…

Superdirective Leaky Radiation from a PT-Synthetic Metachannel
Mehdi Hajizadegan, Pai-Yen Chen
Spectral singularities appearing in parity-time (PT)-symmetric non-Hermitian optical systems have aroused a growing interest due to their new, exhilarating applications, such as bi…

Tunable Terahertz Amplification Based on Photoexcited Active Graphene Hyperbolic Metamaterials
Tianjing Guo, Liang Zhu, Pai-Yen Chen +1
The efficient amplification and lasing of electromagnetic radiation at terahertz (THz) frequencies is a non-trivial task achieved mainly by quantum cascade laser configurations wit…
