Nanophotonics and supramolecular chemistry
Supramolecular chemistry has become a key area in emerging bottom-up nanoscience and nanotechnology. In particular, supramolecular systems that can produce a photonic output are increasingly important research targets and present various possibilities for …
Towards low energy consumption integrated photonic circuits based on Ge/SiGe quantum wells
Despite being an indirect bandgap material, germanium (Ge) recently appeared as a material of choice for low power consumption optical link on silicon. Thanks to a low energy difference between direct and indirect energy bandgap, optical transitions around …
Light manipulation principles in biological photonic systems
The science of light and colour manipulation continues to generate interest across a range of disciplines, from mainstream biology, across multiple physics-based fields, to optical engineering. Furthermore, the study of light production and manipulation is of …
Fano-resonant metamaterials and their applications
New developments in the field of Fano-resonant plasmonic metamaterials are reviewed. The emphasis is on the applications of such artificial electromagnetic materials to a variety of technologically important areas: solar energy harvesting and conversion, …
Comparison of electron energy-loss and quantitative optical spectroscopy on individual optical gold antennas
Using a rather large set of different individual metallic optical antennas, we compare directly measured electron energy-loss spectra with measured quantitative optical extinction and scattering cross-section spectra on the identical antennas. All antenna …
