Plasmonic Antennas Could Deliver Ultrafast Pulses for THz Electronics

Facebook Twitter LinkedIn Email Comments
MUNICH, Germany, June 28, 2018 — In an experiment that combined the advantages of femtosecond nanophotonics with on-chip communications, researchers generated ultrashort electric pulses on a chip using metal structures (i.e., antennas) only a few nanometers in size, then ran the signals a few millimeters above the surface. The signals were then read out in a controlled manner. The researchers demonstrated that femtosecond optical pulses in the NIR could drive electronic on-chip circuits with a prospective bandwidth of up to 10 THz. Physicists from the Technical University of Munich (TUM) exploited femotsecond...Read full article
