Journal ArticleDOI
Resonant plasmonic and vibrational coupling in a tailored nanoantenna for infrared detection.
Frank Neubrech,Annemarie Pucci,Thomas W. Cornelius,Shafqat Karim,Aitzol García-Etxarri,Javier Aizpurua +5 more
TL;DR: In this paper, a novel resonant mechanism involving the interference of a broadband plasmon with the narrowband vibration from molecules is presented, which can be used for sensitive infrared identification of molecular groups.
Journal ArticleDOI
A Switchable Mid-Infrared Plasmonic Perfect Absorber with Multispectral Thermal Imaging Capability.
Andreas Tittl,Ann-Katrin U. Michel,Martin Schäferling,Xinghui Yin,Behrad Gholipour,Long Cui,Matthias Wuttig,Thomas Taubner,Frank Neubrech,Harald Giessen,Harald Giessen +10 more
TL;DR: A switchable perfect absorber with multispectral thermal imaging capability and utilizing the amorphous-to-crystalline phase transition in GST offers switchable absorption with strong reflectance contrast at resonance and large phase-change-induced spectral shifts.
Journal ArticleDOI
Surface-Enhanced Infrared Spectroscopy Using Resonant Nanoantennas.
TL;DR: First applications such as the detection of proteins, the monitoring of dynamic processes, and hyperspectral infrared chemical imaging are discussed, demonstrating the sensitivity and broad applicability of resonant SEIRA.
Journal ArticleDOI
Addressable metasurfaces for dynamic holography and optical information encryption
TL;DR: A dynamic metasurface platform, which allows independent manipulation of addressable subwavelength pixels at visible frequencies through controlled chemical reactions, and suggests a novel route to protect and transmit classified data, where highly restricted access of information is imposed.
Journal ArticleDOI
Optical nanoantennas for multiband surface-enhanced infrared and raman spectroscopy
Cristiano D’Andrea,Jörg Bochterle,Andrea Toma,Christian W. Huck,Frank Neubrech,Frank Neubrech,E. Messina,Barbara Fazio,Onofrio M. Maragò,Enzo Di Fabrizio,Marc Lamy de la Chapelle,Pietro Giuseppe Gucciardi,Annemarie Pucci +12 more
TL;DR: In this article, the plasmonic properties of linear nanoantennas were exploited to make them resonant in both the visible and the infrared, and by rotating the excitation field polarization to selectively take advantage of each resonance.
