From Gadget Lab:
Researchers at MIT have demonstrated the first laser that uses the element germanium.
The laser, which operates at room temperature, could prove to be an important step toward computer chips that move data using light instead of electricity, say the researchers.
“This is a very important breakthrough, one I would say that has the highest possible significance in the field,” says Eli Yablonovitch, a professor in the electrical engineering and computer science department of the University of California, Berkeley who was not involved in the research told Wired.com. “It will greatly reduce the cost of communications and make for faster chips.”
