The domestic microelectronics industry comprises a wide range of developers and manufacturers, each of which has its own specialization. Achievement of the technological sovereignty in the field of microelectronics is impossible without active development and improvement of the specialized processing equipment. How can the standard microelectronics production processes be combined with the advanced laser technologies in a single system? This is precisely the question answered by the laser equipment produced by Laser Center. The company manufactures the equipment for electronic engineering that successfully implements various processes such as demetallization, scribing, green ceramics processing, piercing of corundum ceramics and ferrite, and mesa structuring of semiconductor materials. Laser Center acts as an innovation partner for the Microelectronics-2025 forum. In his interview, Head of the supply department of the company Denis Sergeevich Chekhanovsky highlighted the advantages of laser equipment for manufacturing of the electronic products. Beyond the user convenience, this equipment ensures high reproducibility of results, leading to the increased the efficiency and competitiveness of our microelectronics industry.

The article considers the applicable approaches to the implementation of quantum communications networks in Russia, its architecture, including any relations between the individual elements or levels in the context of available statutory regulations of the quantum communications industry and its common use. The main relevant concepts and definitions are provided.

The article discusses the production features of the optical elements for application in the THz range devices and equipment, describes the properties and specifications of optical materials for its production, and provides the application examples. Special attention is paid to the elements used exclusively in the THz systems and devices.

The parameter selection methods for the onboard basic automatic active optical range sensors and determination of its range characteristic are considered. The paper provides for the dependences and influence of the base value, focal distance and the circle of confusion value on the relative response error of range sensors, as well as selection of these parameters at a given relative error and response distance. The models and optical circuits of the sensors based on a photo- and laser diode developed according to the established method are shown.

The paper discusses the selection of materials for micro-opto-electromechanical switches (MOEMS) used in new generation communication systems. The focus is on the optical and electrical characteristics of materials, such as dielectric permittivity, refractive index, and bandgap. A study of the effect of these parameters on the efficiency of optical systems is carried out. Machine learning methods were used to predict the properties of materials, and promising materials with high dielectric permittivity were identified. The results obtained can be useful in the development of new methods for designing optical and radio-frequency communication components.
