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

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

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-dielectric-metal (ADM) waveguide resonators. The res...
