The paper deals with methods of the realization of the various states of the orbital angular momentum (OAM) of photons. In a method of phase correction (MPC) a stream of photons with a certain mode of orbital angular momentum is used, in the reception module photons with a corresponding OAM mode are selected, and that allows the telecommunications system correction. A technique using a single-axis crystal, to which an electric voltage is applied, allows to create and highlight a few of the OAM states. The analysis of several methods of the OAM states of photons implementations is made. It is shown that the method of MPC, with using of OAM, has certain advantages.
Key words: photon / orbital angular momentum / atmosphere / optical communication line / the correction phase
