New Study Could Help Design Smaller Nanophotonics Devices

The use of barcodes to label and recognize day-to-day items is quite usual similar to a trip to the supermarket. What if those barcodes are shrunk a million times, from millimeter to nanometer scale, to enable their use within living cells to label, recognize, and monitor the building blocks of life, or mixed with inks to avoid counterfeiting.

New Understanding of Light-Matter Interactions in Nanophotonic Materials

Physicists from the University of Konstanz, Ludwig-Maximilians-Universität München (LMU Munich) and the University of Regensburg have successfully demonstrated that ultrashort electron pulses experience a quantum mechanical phase shift through their interaction with light waves in nanophotonic materials, which can uncover the nanomaterials' functionality. The corresponding experiments and results are reported in the latest issue of Science Advances.
