We propose and demonstrate a convenient experimental method to produce perfect vector vortex beams in the…
The predicted Noise Equivalent Power (NEP) of a THz direct detector is validated by means of…
We demonstrate that the far-field terahertz beam generated from a Ti:Sapphire two-color laser-induced filament can exhibit…
Optically-driven photoconductive switches are one of the predominant sources currently used in terahertz imaging systems. However,…
Treating phase in the image plane to be a free parameter, we demonstrate multilevel diffractive lenses…
