Surface Protection and Activation of Mid-IR Plasmonic Waveguides for Spectroscopy of Liquids
Mauro David, Ismael C. Doganlar, Daniele Nazzari +9
Liquid spectroscopy in the mid-infrared spectral range is a very powerful, yet premature technique for selective and sensitive molecule detection. Due to the lack of suitable conce…
Advanced Mid-Infrared Plasmonic Waveguides For On-Chip Integrated Photonics
Mauro David, Davide Disnan, Elena Arigliani +8
Long-wave infrared (LWIR, 8-14 um) photonics is a rapidly growing research field within the mid-IR with applications in molecular spectroscopy and optical free-space communication.…
Resonant Tunneling Diodes Strongly Coupled to the Cavity Field
Benedikt Limbacher, Martin Kainz, Sebastian Schoenhuber +9
We demonstrate Resonant Tunneling Diodes, embedded in double metal cavities, strongly coupled to the cavity field, while maintaining their electronic properties. We measure the pol…
All-Optical Adaptive Control of Quantum Cascade Random Lasers
Sebastian Schönhuber, Nicolas Bachelard, Benedikt Limbacher +7
Spectral fingerprints of molecules are mostly accessible in the terahertz and mid-infrared ranges, such that efficient molecular-detection technologies rely on broadband coherent l…
Picosecond pulses from a mid-infrared interband cascade laser
Johannes Hillbrand, Maximilian Beiser, Aaron Maxwell Andrews +6
The generation of mid-infrared pulses in monolithic and electrically pumped devices is of great interest for mobile spectroscopic instruments. The gain dynamics of interband cascad…
A monolithic frequency comb platform based on interband cascade lasers and detectors
Benedikt Schwarz, Johannes Hillbrand, Maximilian Beiser +6
Optical frequency combs enable all-solid-state spectrometers that will trigger a breakthrough in miniaturization and on-chip integration of mid-infrared sensing technology. Interba…
Suppression of axial growth by boron incorporation in GaAs nanowires grown by self-catalyzed molecular beam epitaxy
Suzanne Lancaster, Heiko Groiss, Tobias Zederbauer +5
The addition of boron to GaAs nanowires grown by self-catalyzed molecular beam epitaxy was found to have a strong effect on the nanowire morphology, with axial growth greatly reduc…
Coherent injection locking of quantum cascade laser frequency combs
Johannes Hillbrand, Aaron Maxwell Andrews, Hermann Detz +2
Quantum cascade laser (QCL) frequency combs are a promising candidate for chemical sensing and biomedical diagnostics, requiring only milliseconds of acquisition time to record abs…
Singular charge fluctuations at a magnetic quantum critical point
L. Prochaska, X. Li, D. C. MacFarland +12
Strange metal behavior is ubiquitous to correlated materials ranging from cuprate superconductors to bilayer graphene. There is increasing recognition that it arises from physics b…
Far-infrared quantum cascade lasers operating in AlAs phonon Reststrahlen band
K. Ohtani, M. Beck, M. J. Süess +6
We report on the operation of a double metal waveguide far-infrared quantum cascade laser emitting at 28 m, corresponding to the AlAs-like phonon Reststrahlen band. To avoid abs…
Spectrally resolved far-fields of terahertz quantum cascade lasers
Martin Brandstetter, Sebastian Schönhuber, Michael Krall +6
We demonstrate a convenient and fast method to measure the spectrally resolved far-fields of multimode terahertz quantum cascade lasers by combining a microbolometer focal plane ar…
Random Lasers for Broadband Directional Emission
Sebastian Schönhuber, Martin Brandstetter, Thomas Hisch +7
Broadband coherent light sources are becoming increasingly important for sensing and spectroscopic applications, especially in the mid-infrared and terahertz (THz) spectral regions…
Rayleigh scattering in coupled microcavities: Experiment
Z. Vörös, P. Mai, M. Sassermann +4
We experimentally analyze Rayleigh scattering in coupled planar microcavities. We show that the correlations of the disorder in the two cavities lead to inter-branch scattering of…
Microcavity-integrated graphene photodetector
Marco Furchi, Alexander Urich, Andreas Pospischil +8
The monolithic integration of novel nanomaterials with mature and established technologies has considerably widened the scope and potential of nanophotonics. For example, the integ…
