This paper describes the advantages of using photonic crystal fibers in telecommunication systems. The relevance of the study is related to the fact that a large number of applications, such as the event in miniature sources of light of several wavelengths of new generation, based on the addition of the active functionality, ultra-sensitive sensors, optical memory functions, require a high quality factor and single-photon sources of light. Photonic crystals are expected to be used in novel optical devices such as non-threshold laser diodes, LEDs single mode, waveguides with small losses low, sharp bends, small prisms and optical integrated circuit. They can even operate as a «left-handed materials», which are able to focus the waves transmitted in the sub-wavelength place due to the negative refraction. Photonic crystals could solve many of the problems that currently limit the speed and capacity of optical communication networks. For example, photonic crystals may be used to create new LEDs and lasers, which emit light in a very narrow wavelength range, as well as optical filters with high selectivity, which can be integrated on a single chip.
