Nonlinear Terahertz Emission in Semiconductor Microcavities [PDF]
, 2013 We consider the nonlinear terahertz emission by the system of cavity polaritons in the regime of polariton lasing. To account for the quantum nature of terahertz-polariton coupling we use the Lindblad master equation approach and demonstrate that quantum

High Resolution Lensless Terahertz Imaging and Ranging [PDF]
IEEE Access, 2019 In this paper, we propose a fast terahertz time-domain imaging method using a radar migration algorithm. We demonstrate high-resolution imaging in reflection without any collimating or focusing optics in the terahertz beam. In the proposed method, the sample is illuminated with a divergent terahertz beam, and the receiver collects both specular and ...

Suspended Tunnel Junction Bolometers For Terahertz Range [PDF]
The Open Applied Physics Journal, 2012 Implementation of high resolution passive THz cameras operated at cryogenic temperatures of a few Kelvin benefits from a large number of pixels. At present, building a cryogenic multiplexed read-out circuit represents a challenging task. Here we propose and demonstrate broadband niobium-based tunnel junction bolometers operating in equilibrium regime ...
