Achieving UV nonlinearity with a wide bandgap semiconductor waveguide

Research

In an international collaboration including EPFL, scientists have achieved giant nonlinearity of UV hybrid light-matter states up to room temperature in a waveguide made of AlInGaN, a wide bandgap semiconductor. The achievement paves the way for new devices in ultrafast chemical and biochemical spectroscopy.
