Theoretical Investigation on Microcavity Coupler for Terahertz Quantum-Well Infrared Photodetectors

IEEE Access, 2020
Resonant behaviors and absorption enhancement of metallic grating-dielectric-metal (GDM) microcavity are theoretically investigated. The GDM structure is treated as periodic unit cells of two serially-connected metal-dielectric-metal (MDM) and air ...

Twenty years of terahertz imaging [Invited].

Optics Express, 2018
The birth of terahertz imaging approximately coincides with the birth of the journal Optics Express. The 20th anniversary of the journal is therefore an opportune moment to consider the state of progress in the field of terahertz imaging.
