Excitation-density-dependent generation of broadband terahertz radiation in an asymmetrically excited photoconductive antenna.

Excitation-density-dependent generation of broadband terahertz radiation in an asymmetrically excited photoconductive antenna.

The generation of terahertz (THz) transients in photoconductive emitters has been studied by varying the spatial extent and density of the optically excited photocarriers in asymmetrically excited, biased low-temperature-grown GaAs antenna structures. We find a pronounced dependence of the THz pulse...
