On the Goal Attainability of the Current Concept of Technological Development. Part II DOI: 10.22184/1993-7296.FRos.2024.18.2.98.114
Institute of Science Development Problems, Russian Academy of Sciences, Moscow, Russia
In continuation of the brief overview of the technological development concept of the Russian Federation until 2030, we have continued to consider the structure, principles and goals described in the Concept. Definitions of the degrading and negative innovations are provided. The conclusions are drawn in relation to the strengths and weaknesses of the Concept (deviation from the standard statistical indicators and application of ill-advised reference points) and the solutions are proposed aimed at the correction of weakness consequences.

Study of Operational Algorithm for Interrogator with Arrayed Waveguide Grating on a Photonic Integrated Circuit DOI: 10.22184/1993-7296.FRos.2024.18.2.122.135
This paper presents analytical and experimental investigations of a fiber Bragg grating interrogator based on the arrayed waveguide grating made with a photonic integrated circuit technology. The key specifications of the interrogator are determined analytically based on the parameters of the arrayed waveguide grating used as a spectral demultiplexer and the photodetector’s operating error. In addition, the detection methods and algorithms for obtaining the reflectance spectrum maximum of fiber Bragg gratings are proposed and evaluated. Experimental measurements of the fiber Bragg grating central wavelength using the proposed algorithm are carried out, including calibration and measurement procedures using the data obtained under the influence of temperature and mechanical stress on the fiber Bragg grating. The system performance is experimentally confirmed with the accuracy of determination of a central wavelength of fiber Bragg grating reflection peak not less than 61 pm.

MCP-PMT – Photon Counting UV-VIS Detectors DOI: 10.22184/1993-7296.FRos.2024.18.2.160.165
The development of MCP-PMT – photon counting UV–VIS detectors for optical-physical measurements is reported. MCP-PMTs design and technology features are described, which allow achieving high peak-to-valley ratio, low dark count rate and longer lifetime. We present different versions of PMT constructions (in the form of vacuum units and with a voltage divider integrated into a single housing with a vacuum unit).

Long-Focal Length Catadioptric Lenses DOI: 10.22184/1993-7296.FRos.2024.18.2.152.158
The design of long-focal length catadioptric lenses for the visible and infrared ranges (VIS, SWIR, MWIR and LWIR) is proided. The front group of all lenses is similar and consists of 2 mirrors, with the first (prime) mirror having a diameter of 150 mm. The diameter of the mirror is selected based on the requirements for lens aperture and possible production of the mirror. In addition, the same diameter of the primary mirror, if necessary, allows to combine several channels (TV and SWIR, TV and LWIR) into one. The article describes a television and SWIR lenses with a focal point of 600 mm and a relative aperture of F/4, a MWIR lens with a focal point of 400 mm and a relative aperture of F/4, and a LWIR lens with a focal point of 250 mm and a relative aperture of F/1.6. The design options for a catadioptric zoom and multi-channel lenses with a focal point of 400–800 mm and a relative aperture F/5-F/10 are indicated.

Shedding Light on DNA Origami: Practice DOI: 10.22184/1993-7296.FRos.2024.18.2.166.174
Modern photonics requires technologies for the reproducible and controllable production of nanostructures, since many interesting and important optical processes occur on the subdiffractional scale characteristic for such structures. However, working with light at nanometer distances requires nanometer precision in object positioning, which is extremely difficult to achieve using standard methods. One of the new approaches that can become a response to this challenge is the use of DNA origami: structure of the polymer DNA molecule allows, on the one hand, chemically “tuning” of its geometry to obtain arbitrary shape on a nanometer scale, and on the other, addressability of DNA molecule allows nanoobjects to be placed at any position along its chain. This review considers some practical issues related to DNA origami preparation.
