Carsten Sönnichsen,S. Geier,N. E. Hecker,G. von Plessen,Jochen Feldmann,Harald Ditlbacher,Bernhard Lamprecht,Joachim R. Krenn,Franz R. Aussenegg,Vanessa Z.-H. Chan,Joachim P. Spatz,Martin Möller +11 more
TL;DR: In this article, a simple, fast, and flexible technique to measure optical scattering spectra of individual metallic nanoparticles was developed to measure the effect of particle diameter on the dephasing time of the particle plasmon resonance in gold nanoparticles.
Journal ArticleDOI
An optically controllable terahertz filter
Imke. H. Libon,S. Baumgärtner,M. Hempel,N. E. Hecker,Jochen Feldmann,Martin Koch,Philip Dawson +6 more
TL;DR: Using a mixed type-I/type-II GaAs/AlAs multiple-quantum-well sample, an optically controllable and tunable terahertz (THz) filter was demonstrated in this paper.
Proceedings ArticleDOI
THz spectroscopy of polar liquids
Imke. H. Libon,M. Hempel,S. Seitz,N. E. Hecker,Jochen Feldmann,A. Hayd,G. Zundel,Daniel M. Mittleman,Martin Koch +8 more
TL;DR: In this paper, the mesoscopic structure of water has been investigated using Thz-time domain spectroscopy (THz-TDS) based on photoconductive dipole antennas gated by 150 femtosecond laser pulses.
Book ChapterDOI
THz Imaging Of Biological Samples
Martin Koch,K. Schmalstieg,P. Knobloch,Stefan Hunsche,Martin C. Nuss,E. Rehberg,I. Sautter,J. Fromm,M. Hempel,R. Haferkorn,Imke. H. Libon,N. E. Hecker,Jochen Feldmann +12 more
TL;DR: In this article, a typical THz-TDS experimental setup for generation and detection of THz waveforms and configured for THzimaging is presented, along with three examples in which imaging on biological samples can be useful and present their experimental results on these materials using THzTDS.
Proceedings ArticleDOI
Low-power optically controllable THz attenuator
N. E. Hecker,Imke. H. Libon,M. Hempel,S. Baumgaertner,Martin Koch,Philip Dawson,Jochen Feldmann +6 more
TL;DR: In this article, a low power, optically-controllable, THz attenuator capable of high contrast ratios using a mixed type-I/type-II quantum well sample was demonstrated.
