Classification: CPC G  B | IPC B  G

Claim 0:
1. An optical device comprising:
a generally planar substrate;
a plurality of micro-structures having an arcuate cross-sectional shape disposed on at least a portion of the planar substrate and arranged in a repeating pattern; and
a plurality of nano-structures conformally disposed on at least a portion of the disposed plurality of microstructures, the plurality of nanostructures:
providing additional means of directing incident light on the plurality of nano-structures to a space above or below the device;
having a thickness of less than 50 μm and more than 1 μm; and
having at least one feature size less than 500 nm;

the device being configured such that when visible light is incident over the device, the plurality of nano-structures provides means of creating structural colors.
