When the beams of light (e.g. laser beams) propagate through homogeneous materials, they broaden diffractively in propagation. One can not focus tightly the laser beam on the surface of the Moon. It comes out, however, that the periodic photonic materials can suppress the diffraction. Such materials are called “photonic crystals”. We investigate the non-diffractive or sub-diffractive propagation of laser light in such photonic crystals. We construct novel devices (linear and nonlinear resonators, parametric amplifiers, and others) where the non-diffractive light behaviour is utilized. Not only the light waves, but all other waves, like sound waves, or matter waves, diffract. We apply our experience in the field of “sub-diffractive light waves” to the fields of the other waves, and we investigate sub-diffractive propagation of sound waves in so called “sonic crystals”, as well as sub-diffractive dynamics of matter waves in so called periodically modulated Bose-Einstein condensate.
