Thin films were prepared based on cellulose polymer doped with different ratios of natural dye derived from Portulaca grandiflora concentrations. The polymer and natural dye were extracted from eco-friendly materials—the cell walls of millet husks and Portulaca grandiflora, respectively. The spray pyrolysis technique was applied to prepare thin film samples to control the film morphology and reduce the roughness of the surface. Optical microscope and Fourier transform infrared were used to analyse structural, morphological, and functional groups for all samples, respectively. The peak absorbance, extinction coefficient, optical bandgap, Urbach energy, and optical conductivity for the thin films were determined using ultraviolet-visible spectroscopy. The results show an enhancement in the optical characteristics when the natural cellulose is doped with a dye. Doping cellulose with 5% P. grandiflora has led to a considerable reduction in the energy bandgap (to 1.95 eV), compared to the sample doped with 1%.

The article presents an overview and a classification of X-ray detection methods. The main motivation for its preparation was the need to select a suitable and useful method for detecting signals from a currently developed miniature micro-electro-mechanical system (MEMS) X-ray source. The described methods were divided into passive and active ones, among which can be distinguished: chemical, luminescent, thermo-luminescent, gas ionization, semiconductor, and calorimetric methods. The advantages and drawbacks of each method were underlined, as well as their usefulness for the characterisation of the miniature MEMS X-ray source.

In this paper, the designing and simulation of 400 Gbps polarisation division multiplexing-quadrature amplitude modulation-orthogonal frequency division multiplexing (PDM-4QAM-OFDM)-based inter-satellite optical wireless communication (IsOWC)/mechatronic telecommunication system for improving the link information carrying capacity was carried out. With quadrature amplitude modulation (QAM) encoding, the performance of the executed system has been addressed using metrics such as signal to noise ratio (SNR) and total received power (RP). The performance with suggested system has been examined in relation to the effects of various factors such as operating wavelength, transmission power, and receiving pointing error angle. Moreover, a better identification method for improving connection reach between mechatronic devices/satellites has been revealed in this study. A performance comparison of the proposed system with other implemented approaches has been made in the final step

Local weather conditions have an impact on the availability of free-space optical (FSO) communication. The variation in meteorological parameters, such as temperature, humidity, and wind speed, leads to variations of the refractive index along the transmission path. These refractive index inhomogeneities produced by atmospheric turbulence induce optical turbulence which is responsible for random fluctuations in the intensity of the laser beam that carries the signal (irradiance) called scintillations that can significantly degrade the performance of FSO systems. This paper aims to investigate the feasibility of deploying FSO communication technology under scintillation effects in any urban region and atmospheric environment. To achieve that, firstly by utilizing the Hufnagel-Vally day with the Sadot and Kopeika models together, the scintillation strength for a specified region, Sulaimani City in north-eastern Iraq as an example, has been estimated through the calculation of the refractive index structure parameter (Cn2) over a period of 10 years and it was found to be at the strong turbulence level. Secondly, from the same estimated parameter, the scintillation attenuation of the signal carrying the laser beam intensity can be calculated to investigate the feasibility of FSO communication using Optysistem-7 software. The optimal link distance for north-eastern Iraq (Sulaimani City) has been found to be within the limit of about 5.5 km. Analysing the max. Q-factor, bit-error rate and signal to noise ratio for an average of 120 months between 2013–2022 assessed the best and worst seasons for FSO.

Most automotive electronic components can cause electromagnetic interference, that can cause power electronic circuits to become unstable. As per electromagnetic compatibility (EMC) standards, these electronic circuits should meet the specifications which are not achieved under some conditions. In this paper, the conducted emissions (CEs) are generated due to the switching of a buck converter, which often occurs in automotive electronics. The noise source was found to be due to the presence of common mode currents which largely affects the performance of EMC. Two types of filtering techniques were analysed and designed, and the results were compared to find an effective filtering solution to mitigate the effects of CE due to a common mode noise for the frequency range from 150 kHz to 108 MHz according to the International Special Committee on Radio Interference (CISPR25) standard. The capacitive and parasitic impedance were calculated and then used in the simulation. Finally, the simulated and measured results are presented. The noise level can be minimized by as much as 50 dB, which is an efficient noise reduction value.

Additional info

Opto-Electronics Review was established in 1992 for the publication of scientific papers concerning optoelectronics and photonics materials, system and signal processing. This journal covers the whole field of theory, experimental verification, techniques and instrumentation and brings together, within one journal, contributions from a wide range of disciplines. Papers covering novel topics extending the frontiers in optoelectronics and photonics are very encouraged. The main goal of this magazine is promotion of papers presented by European scientific teams, especially those submitted by important team from Central and Eastern Europe. However, contributions from other parts of the world are by no means excluded.

Articles are published in OPELRE in the following categories:

-invited reviews presenting the current state of the knowledge,

-specialized topics at the forefront of optoelectronics and photonics and their applications,

-refereed research contributions reporting on original scientific or technological achievements,

-conference papers printed in normal issues as invited or contributed papers.

Authors of review papers are encouraged to write articles of relevance to a wide readership including both those established in this field of research and non-specialists working in related areas. Papers considered as “letters” are not published in OPELRE.

Opto-Electronics Review is published quarterly as a journal of the Association of Polish Electrical Engineers (SEP) and Polish Academy of Sciences (PAS) in cooperation with the Military University of Technology and under the auspices of the Polish Optoelectronics Committee of SEP.

• Opto-Electronics Review is a single-blind review journal.

• Papers will be refereed by at least 2 experts as suggested by the editorial board.

• In addition, Editors will have the option of seeking additional reviews when needed. Authors will be informed when Editors decide further review is required.

• All publication decisions are made by the journal’s Editor-in-Chief based on the referees’ reports. Authors of papers that are not accepted are notified promptly.

• All submitted manuscripts are treated as confidential documents. We expect reviewers to treat manuscripts as confidential material.

• Editors and reviewers involved in the review process should disclose conflicts of interest resulting from direct competitive, collaborative, or other relationships with any of the authors, and remove oneself from cases in which such conflicts preclude an objective evaluation. Privileged information or ideas that are obtained through peer review must not be used for competitive gain.

• A reviewer should be alert to potential ethical issues in the paper and should bring these to the attention of the editor, including any substantial similarity or overlap between the manuscript under consideration and any other published paper of which the reviewer has personal knowledge. Any statement, observation, derivation, or argument that had been previously reported should be accompanied by the relevant citation.

• Personal criticism is inappropriate.


Reproducing text from other papers without properly crediting the source (plagiarism) or producing many papers with almost the same content by the same authors (self-plagiarism) is not acceptable. Submitting the same results to more than one journal concurrently is unethical. Exceptions are the review articles. Authors may not present results obtained by others as if they were their own. Authors should acknowledge the work of others used in their research and cite publications that have influenced the direction and course of their study.

Plagiarism is not tolerated. All manuscripts submitted to Opto-Electronics Review will be checked for plagiarism (copying text or results from other sources) and self-plagiarism (duplicating substantial parts of authors’ own published work without giving the appropriate references) using the CrossCheck database (iThenticate plagiarism checker).

Duplicate submission

Simultaneous submissions of the same manuscript to different journals will not be tolerated. The submitted article will be removed without consideration.

Corrections and retractions

All authors have an obligation to inform and cooperate with journal editors to provide prompt retractions or correction of errors in published works.

• The journal will issue retractions if:

• There is clear evidence that the findings are unreliable, either as a result of misconduct (e.g., data fabrication or honest error - miscalculation or experimental error);

• The findings have previously been published elsewhere without proper cross-referencing, permission or justification (i.e., cases of redundant publication);

• It constitutes plagiarism;

• It reports unethical research.

• The journal will issue errata, if:

• A small portion of an otherwise reliable publication proves to be misleading (especially because of honest error);

• The author list is incorrect.

Other forms of misconduct include failure to meet clear ethical and legal requirements such as misrepresentation of interests, breach of confidentiality, lack of informed consent and abuse of research subjects or materials. Misconduct also includes improper dealing with infringements, such as attempts to cover up misconduct and reprisals on whistleblowers.

The primary responsibility for handling research misconduct is in the hands of those who employ the researchers. If a possible misconduct is brought to our attention, we will seek advice from the referees and the Editorial Board. If there is the evidence, we will resolve the matter by appropriate corrections in the printed and online journal; by refusing to consider an author's future work and by contacting affected authors and editors of other journals.
