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

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.
