[Quantum well LED optical switch performance record refreshed] On November 11, scientists from the University of Illinois at Urbana-Champaign and the University of Notre Dame collaborated to set a new world record for the optical switch performance of quantum well light-emitting diodes (LEDs). The gallium nitride quantum well micro-LED they developed has a light modulation bandwidth of 2.75 GHz and a power consumption of only 25 milliwatts. It is expected to become a low-power alternative to lasers in short-distance optical interconnections in data centers. The relevant paper was published in the new issue of "IEEE Electronic Devices Letters".
