Coupling Microlasers Leads to ’Blackout’

VIENNA, April 25, 2012 — By coupling two microlasers together, one would expect more light to be emitted than from a single pumped laser alone. But coupling such lasers can, paradoxically, lead to a "blackout" where they shut each other off. The finding could prove significant for technologies that couple electronics and photonics. Scientists at the Vienna University of Technology (TU Vienna), working with colleagues at Princeton and Yale universities in the US and ETH Zurich, discovered the "laser blackout" effect by using new methods developed at TU Vienna to solve the complicated equations that describe the...Read full article
