Abstract
An optical device includes a layer having a face configured to be traversed by light at an operating wavelength. The face of the layer includes a fractal structure lacking rotational symmetry such as a fractal structure that corresponds to a fractal expressed in an L-system. The fractal structure is formed by recesses that penetrate into the layer from the face. The recesses have a depth which is less that a thickness of the layer.
