Compared with their metal or dielectric counterparts, hybrid metasurfaces resulting from the combination of dielectric and metallic nanostructures can offer increased possibilities for interactions between modes present in the system. Here, we investigate the interaction between lattice resonances in a hybrid metal-dielectric metasurface obtained from a single-step nanofabrication process. Finite-difference time domain simulations show the avoided crossing of the modes appearing in the wavelength-dependent absorptance inside the Ge upon variations in a selected geometry parameter as evidence for strong optical coupling. We find good agreement between the measured and simulated absorptance and reflectance spectra. Our metasurface design can be easily incorporated into a top-down optoelectronic device fabrication process with possible applications ranging from on-chip spectroscopy to sensing.}, language = {en} } @misc{SchlipfBerkmannYamamotoetal., author = {Schlipf, Jon and Berkmann, Fritz and Yamamoto, Yuji and Reichenbach, Marc and Veleski, Mitko and Kawaguchi, Y. and M{\"o}rz, Florian and Tomm, Jens W. and Weißhaupt, David and Fischer, Inga Anita}, title = {Robust Si/Ge heterostructure metasurfaces as building blocks for wavelength-selective photodetectors}, series = {Applied Physics Letters}, volume = {122}, journal = {Applied Physics Letters}, number = {12}, issn = {1077-3118}, doi = {10.1063/5.0134458}, language = {en} }
