Study shows optical excitation of hot carriers enables ultrafast dynamic control of nanoscale plasmons

Physorg.com - 17 мая, 2024 - 20:09
Photonic computing, storage, and communication are the foundation for future photonic chips and all-optical neural networks. Nanoscale plasmons, with their ultrafast response speed and ultrasmall mode volume, play an important role in the integration of photonic chips. However, due to the limitations of materials and fundamental principles in many previous systems, they are often incompatible with existing optoelectronics, and their stability and operability are greatly compromised.

Using DNA origami, researchers create diamond lattice for future semiconductors of visible light

Physorg.com - 17 мая, 2024 - 18:22
The shimmering of butterfly wings in bright colors does not emerge from pigments. Rather, photonic crystals are responsible for the play of colors. Their periodic nanostructure allows light at certain wavelengths to pass through while reflecting other wavelengths. This causes the wing scales, which are in fact transparent, to appear so magnificently colored.
