Ultrasensitive terahertz sensing with high-Q Fano resonances in metasurfaces
TL;DR: In this paper, a planar terahertz metamaterial was used for ultra-sensitive sensing in the fingerprint region of the tera-hertz regime, where the low-loss quadrupole and Fano resonances with extremely narrow linewidths were used to measure the minute spectral shift caused due to the smallest change in the refractive index of the surrounding media.

TL;DR: A monolithic terahertz injection laser that is based on interminiband transitions in the conduction band of a semiconductor (GaAs/AlGaAs) heterostructure is reported, which is very promising for extending the present laser concept to continuous-wave and high-temperature operation, which would lead to implementation in practical photonic systems.
