НОВАЦИОННЫЕ МЕТОДЫ ГЕНЕРАЦИИ МОДЫ ОАМ ФОТОНОВ ДЛЯ ОПТИЧЕСКИХ ЛИНИЙ СВЯЗИ

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) with the OAM is used a stream of photons with a certain mode of orbital angular moment, in the reception by the module are selected photons with a corresponding fashion the OAM is that it allows for the adjustment of the system of telecommunications. A technique using a single-axis crystal, to which is applied an electric voltage, allows to you to create and highlight a few of the states the OAM. It is shown also the method of using sub-wavelength grating based on dielectric structures in the form of an array of nano ? hairs.The analysis is made of several methods of implementation of the OAM states of photons. It is shown that the method of MPC, with using of OAM, has certain advantages.
