The Community Has Been Formed and the Questions Have Been Formulated. What Comes Next? DOI: 10.22184/1993-7296.FRos.2026.20.5.320.329
In the Russian Federation, a qualitative leap has taken place in the structuring of activities in the field of photonics. However, there are some specific problems that are associated with the production and application of photonic integrated circuits (PICs). In order to systematize the work on the development of photonic elements in accordance with their demand, it is proposed to begin the formation of a nomenclature (terms) for the photonic component base. The arguments substantiating the necessity of the proposed structuring tool are presented in this paper.

Laser Annealing of Silicon Carbide for The Formation of Ni/SiC Ohmic Contacts DOI: 10.22184/1993-7296.FRos.2026.20.5.342.349
The study investigates laser annealing of silicon carbide for the formation of Ni/SiC ohmic contacts. The aim of the work was to confirm the feasibility of forming ohmic contacts by laser annealing and to identify ranges of processing parameters that provide linear and symmetric current-voltage (I–V) characteristics and low specific contact resistivity. Contact structures with different intercontact spacings were used for experimental verification. The results were evaluated by analyzing and classifying the I–V characteristics, followed by application of the transmission line method (TLM) for quantitative determination of the contact parameters. The experimental results showed that contacts exhibiting ohmic behavior are formed not within a single processing window, but within several distinct ranges of laser-processing parameters. The identified processing ranges can serve as a basis for further optimization of the process with consideration of the properties of the starting material, metallization, and contact geometry. The developed software and laser system provide accurate positioning and reproducible definition of the geometry of the treated areas, enabling efficient processing of series of test structures and providing a basis for further development of an industrial laser annealing system.

Laser Drilling of Microholes in Transparent Materials: From Q-switch to Ultrafast Lasers – a Review This review presents advanced developments in the field of laser micro-hole drilling in transparent materials such as glass and crystals, which are used in microfluidics, photonics, and medical devices. The large band gap of transparent materials leads to weak absorption of laser radiation, which creates problems with laser drilling. The article traces the evolution of technologies from the use of Q-switched lasers to picosecond and femtosecond lasers, which minimize thermal damage, heat-affected zone and crack formation. The influence of pulse duration, repetition frequency, and wavelength on the quality of the micro-holes in terms of aspect ratio, taper angle, and thermal impact zone are analysed. Various drilling techniques, including percussion, trepanning, and spiral drilling, are reviewed. The article discusses approaches for laser drilling of transparent materials and suggests new intelligent laser feedback systems for precision manufacturing of the future.

«Radio-photonics‑2026»: Who Is Responsible for Coordinating Efforts In the Development of Domestic Radiophotonics or “The Moment of Truth” DOI: 10.22184/1993-7296.FRos.2026.20.5.334.341
The history of the development of microwave photonics in Russia spans several decades. During this time, scientific schools have been formed, and fundamental principles have been developed for the creation of narrow-band lasers, waveguide structures with low optical losses, and methods for integrating lasers, modulators, and photodetectors on a chip. However, despite the clear advantages of microwave photonics, such as high speed, wide bandwidth, low weight and size, and noise immunity, the systematic transition from laboratory prototypes to mass-produced products has not yet been fully achieved in Russia.

For automation of cartridge case visual inspection, an algorithm based on convolutional neural networks is proposed, providing the defect detection efficiency of up to 90%. The systems have undergone testing and are currently used at the domestic industrial facilities.

Photonic neural networks are currently receiving increased attention due to the prospects of increasing computation speed and reducing energy consumption through the use of photons instead of electrons that in the future may solve the problem of slowing growth in the clock rate of digital processors (CPUs) and the challenge of reducing their power consumption. In turn, it will lead to the reduced data processing time in the fiber-optic data network nodes and increased bandwidth of networks with the comprehensive structures. This article provides an overview of experimentally achieved specifications of nonlinear devices based on the common integrated photonics materials. The ultimately achievable characteristics of nonlinear photonic devices and the challenges facing their implementation are analyzed.
Analysis of the literary data and numerical estimates demonstrates that the devices based on semiconductor photonic crystal resonators have the greatest potential for nonlinear photonics.

Domestic UV–Curable Coatings for Optical Fiber DOI: 10.22184/1993-7296.FRos.2026.20.5.364.370
The article presents a review of domestic developments in coatings for fiber optics (FO). The results of testing primary and secondary UV- and LED-curable coatings for optical fiber, namely Acrolat OVP‑1, Acrolat OVP‑1 LED, Acrolat OVP‑2, and Acrolat OVP‑2 LED, are reported. These materials are analogues of Covestro products DeSolite DS 1004 and DS 2015 in terms of technological, thermomechanical, and performance characteristics. Compositions of the Acrolat OVP‑1 and Acrolat OVP‑2 types are characterized by rapid curing under UV irradiation in the wavelength range of 200–400 nm and are suitable for both wet-on-wet and wet-on-dry application processes. Currently, these materials are undergoing industrial trials. Samples of quartz-quartz optical fiber coated with these materials meet established geometric and optical requirements, and also withstand the specified rewinding force and retain their properties after bending tests, demonstrating performance comparable to fibers manufactured with imported coatings.
