Intense terahertz generation based on the photo-dember effect

Optics InfoBase Conference Papers (2010)

Authors:

G Klatt, F Hilser, W Chao, R Gebs, A Bartels, K Huska, U Lemmer, G Bastian, MB Johnston, M Fischer, J Faist, T Dekorsy

Abstract:

We demonstrate a new scheme for generating THz radiation based on the photo-Dember effect in lateral geometry. By micro-structuring a semiconductor surface we achieve strongly enhanced THz emission comparable to high-efficiency externally biased photoconductive emitters. © 2010 Optical Society of America.

Terahertz radiation from multiplexed photo-dember currents

Optics Infobase Conference Papers (2010)

Authors:

G Klatt, F Hilser, W Qiao, R Gebs, A Bartels, K Huska, U Lemmer, G Bastian, MB Johnston, M Fischer, J Faist, T Dekorsy

Abstract:

We investigate a novel method to generate intense THz radiation by multiplexing coherent photo-Dember currents in a lateral geometry. These THz emitters are passive devices with a peak frequency at about 1.5 THz. © OSA / UP 2010.
