Subpicosecond, freely propagating electromagnetic pulse generation and detection using GaAs:As epilayers
(AIP Publishing, 1991-04-08)
Using GaAs epilayers with arsenic precipitates (GaAs:As) as the photoconductive material in a broad-band optoelectronic terahertz beam system, we have generated and detected freely propagating, subpicosecond electromagnetic ...
