Description: The current state and development of optical links, components of micropower optocouplers (a radiator, a photodetector) for their use are analyzed: between blocks of digital integrated circuits (ICs), crystal-IC housing connections and directly on the surface of an IC chip. The frequency limits for metal guide media (GM) and the main factors determining them are considered; indicated these disadvantages and the advantages of optical GM. A short analysis of the elements of micro-power optocouplers and their VHF components, UHF bands, optoelectronic logic circuits based on them (of the nOR- NOT type) and the designs proposed by the author and their models was carried out. Prospective constructive- technological solutions (CTS) and the rationale for their implementation in modern developments of planar optoelectronic digital ICs are proposed; approaches and a number of designs of well-known manufacturers with the use of optical GM for IC are considered, conclusions are formulated.
