Optical gratings are periodic structures for light diffraction. Such nanostructures are created with laser interference lithography, among other methods.
The term optical grating is synonymous with diffraction grating.
Through multiple exposure with intermittent rotation of the resist sample, grid structures modulated in two dimensions are produced. Tilting the substrate allows prismatic or sawtooth structures to be implemented.
In thin-film PV cells and organic PV cells, for example, diffraction gratings can increase energy efficiency while lengthening the light paths in the PV layer. temicon is a manufacturer and supplier of nano line structures for creating polarization films, nano-wire grid polarizers, transparent electrodes and metal mesh surfaces.
