Abstract
Chiral liquid crystal with a short pitch can form gratings with very
small period and lead to efficient diffraction over large angels.
With this approach flat optical devices may be created for
incoupling and outcoupling of light in waveguides. The efficiency
in a narrow wavelength range is high, which makes this approach
very promising for augmented reality displays.
