What They Say
Scientists in two German institutes have developed a new optical diffuser that uses silicon nanoparticles that create a metasurface that can redirect specific wavelengths of light. The groups see applications in transparent screens and also in AR devices. The particles are arranged in a ‘disordered, but carefully planned manner’.
Dennis Arslan, a doctoral researcher at Jena University and second main author, explained:
“We fabricated metasurface diffusers that appear to be equally bright from all directions when looked at with the naked eye. The remarkable aspect is that this happens in a layer that is 0.2 micrometers in thickness only. The diffusers scatter light of a specific color and let other wavelengths pass undisturbed.”
The work is described in Advanced Materials.
What We Think
I was holding this one for a possible Display Daily article, but then realised that it was probably just over the edge of my understanding! (BR)
