Three-dimensional quantum photonic elements based on single nitrogen vacancy-centres in laser-written microstructures
Andreas W. Schell, Johannes Kaschke, Joachim Fischer +4
A fully integrated quantum optical technology requires active quantum systems incorporated into resonant optical microstructures and inter-connected in three dimensions via photoni…
Negative-index bi-anisotropic photonic metamaterial fabricated by direct laser writing and silver shadow evaporation
Michael S. Rill, Christine Plet, Michael Thiel +3
We present the blueprint for a novel negative-index metamaterial. This structure is fabricated via three-dimensional two-photon direct laser writing and silver shadow evaporation.…
Past Achievements and Future Challenges in 3D Photonic Metamaterials
Costas M. Soukoulis, Martin Wegener
Photonic metamaterials are man-made structures composed of tailored micro- or nanostructured metallo-dielectric sub-wavelength building blocks that are densely packed into an effec…
On three-dimensional dilational elastic metamaterials
Tiemo Bückmann, Robert Schittny, Michael Thiel +3
Dilational materials are stable three-dimensional isotropic auxetics with an ultimate Poisson's ratio of -1. We design, evaluate, fabricate, and characterize crystalline metamateri…
Broadband terahertz generation from metamaterials
Liang Luo, Ioannis Chatzakis, Jigang Wang +4
The terahertz spectral regime, ranging from about 0.1 to 15 THz, is one of the least explored yet most technologically transformative spectral regions. One current challenge is to…
Micro-Structured Two-Component 3D Metamaterials with Negative Thermal-Expansion Coefficient from Positive Constituents
Jingyuan Qu, Muamer Kadic, Andreas Naber +1
Controlling the thermal expansion of materials is of great technological importance. Uncontrolled thermal expansion can lead to failure or irreversible destruction of structures an…
