The intensity shaper can convert an input Gaussian beam to precisely direct light.

Caption

The intensity shaper can convert an input Gaussian beam to precisely direct light, as in (a) “smiley” light distribution. Precision arrangement of voxels is achieved using ultrafast direct laser writing. (c) Each voxel is a micron-sized element with (b) a specific refractive index profile along the x and y axes.
