Research Bits: Feb. 27


Phonon-magnon reservoir Researchers from TU Dortmund, Loughborough University, V. E. Lashkaryov Institute of Semiconductor Physics, and University of Nottingham were inspired by the human eye to propose an on-chip phonon-magnon reservoir for neuromorphic computing. In reservoir computing, input signals are mapped into a multidimensional space, which is not trained and only expedites recogni... » read more

Maximizing Design Flexibility For Multi-Layered And Diffractive Optical Components


A broad range of optical devices use nanostructured layers and surfaces to manipulate beams of light through diffraction and interference. Example devices include diffraction gratings, metasurfaces, diffractive optical elements, and metalenses. While the purpose and function of these devices can differ, they offer similar challenges from the point of view of simulation. In this white paper, ... » read more

Machine Learning-Based Optimization Of Chiral Photonic Nanostructures: Evolution- And Neural Network-Based Design


Chiral photonics opens new pathways to manipulate light-matter interactions and tailor the optical response of metasurfaces and -materials by nanostructuring nontrivial patterns. Chirality of matter, such as that of molecules, and light, which in the simplest case is given by the handedness of circular polarization, have attracted much attention for applications in chemistry, nanophotonics and ... » read more

Power-Performance Bits: Dec 3


In this week’s edition of Power/Performance Bits we look at two very different types of antennas, in one case a combined antenna and solar panel and in the second nanoantennas that can create holograms. Combining Antennas with Solar Panels When it comes to satellites weight is everything, and historically telecommunication antennas and solar cells have never really worked well together, a... » read more
