NANOMATERIALS AND OPTOELECTRONICS IN HIGH-SPEED COMMUNICATION SYSTEMS

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The article considers issues concerning increase in capacity of fiber-optic systems used on railways. The main directions of increasing information transmission speed are reviewed and analyzed, particularly enhancement of high-speed response of optical modulators and photodetectors through improving functional environment of optoelectronic devices and reducing inertia of the material. For this purpose, new materials are proposed in the form of multilayer nanostructures, along with manufacturing techniques and methods of assessing their quality characteristics required for design of new optoelectronic devices, that will positively affect railway communication systems’ performance. Keywords: railways, communication channels, information network, isotope effect, bandwidth, nanostructure, fiber-optic system, optoelectronic devices.
