Fast detector of the ellipticity of infrared and terahertz radiation based on HgTe quantum well structures [PDF]
, 2008 We report a fast, room temperature detection scheme for the polarization ellipticity of laser radiation, with a bandwidth that stretches from the infrared to the terahertz range. The device consists of two elements, one in front of the other, that detect

Terahertz plasmonic laser radiating in an ultra-narrow beam
, 2016 Plasmonic lasers (spasers) generate coherent surface-plasmon-polaritons (SPPs) and could be realized at subwavelength dimensions in metallic cavities for applications in nanoscale optics. Plasmonic cavities are also utilized for terahertz quantum-cascade
