Room-temperature, continuous-wave Terahertz generation in free-space with an intersubband mid-infrared photomixer

Q. Lin, J-F. Lampin, G. Ducournau +4

We demonstrate a Terahertz photomixer pumped by mid-infrared photons at 10$\hat{I}¼$m wavelength. The device is based on a dual-antenna architecture, in which a two-dimensional array of…
