Abstract: We discuss particular realizations of optical elements and devices that enable one to break the diffraction limit. A planar binary photonic crystal lens, a zone plate and a binary spiral microaxicon are considered as examples of microoptics devices for subwavelength focusing of laser light.

Keywords: microoptics, diffraction limit, subwavelength focusing, photonic crystal lens, zone plate, spiral microaxicon.
