Researchers at Northwestern University have created a nanolaser that can be used in living tissues without harming them. Developed in conjunction with a team from Columbia University, the nanolaser can be 50 nm to 150 nm thick, which allows it to fit and fully function inside living tissues.
“Our tiny lasers operate at powers that are orders of magnitude smaller than observed in any existing lasers,” said P. James Schuck, an associate professor of mechanical engineering at Columbia and co-leader of the study.
The nanolaser can operate in “extremely confined spaces” including quantum circuits and microprocessors for ultrafast and low-power electronics. It is made mainly of glass, which itself is…READ MORE
