This type of optical integrated device is called transistor laser (TL). First, the rate equation of LD has been solved to obtain its transfer function. Second, the overall transfer function of the whole structure has been analyzed numerically. The effect of HBT cutoff frequency on the amplitude and phase frequency response has been studied. The obtained results show that HBT has a strong influence on the device performance. In particular, higher values of HBT cutoff frequency result in lower amplitudes and higher phase values in the low-frequency range. The device is stable and has a fast response and high optical gain at higher frequencies. Therefore, it can be used as an optical amplifier or optical switch in high-speed optical systems.","PeriodicalId":21598,"journal":{"name":"Semiconductor physics, quantum electronics and optoelectronics","volume":"58 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91522014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the experiments showed the complex nature of the complex Kerr angle dispersion curves. A quantum mechanical formalism for degenerate and non-degenerate Landau levels for quasi-free electrons in ferromagnetic material has been developed in order to analyze the experimental data. The equivalence of relations for off-diagonal dielectric tensor elements for non-degenerate Landau levels to the classical case of the motion of quasi-free electrons along circular trajectories in a magnetic field has been theoretically shown. The degenerate Landau levels in this approach are the result of motion of electrons in small confined volumes near rare-earth alloy atoms. Rotation of light polarization occurs in this case due to transitions between subbands having different magnetic quantum numbers. This theoretical approach allowed us to interpret in detail shapes and sign of the complex Kerr angle dispersion curves, which actually include the contributions of optical transitions between degenerate and non-degenerate energy levels. The complex Kerr angle sign is determined by the magnetization magnetic field direction for non-degenerate Landau levels and the Hund rule for degenerate Landau levels.","PeriodicalId":21598,"journal":{"name":"Semiconductor physics, quantum electronics and optoelectronics","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76265241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These barriers are caused by the difference in properties inherent to layers of porous matrix. Considered here has been the prospect of creating the new devices based on the second-class conductors capable to control the direction and magnitude of the current flow in these conductors that are in a liquid state (in electrolytes).

In these electro-optical systems, the spectral flux of sensing radiation is formed using multispectral laser signals based on a priori information about the spectral reflectance of the target and background. The sensing signal formed in this way ensures maximum suppression of the background signal at the output of system with minimal attenuation of the target signal. The influence of atmospheric radiation attenuation on operation of an active electro-optical system with dynamic spectral processing has been analyzed. It has been shown that the laser radiation attenuation in the atmosphere significantly affects the efficiency of dynamic spectral processing of optical signals (leads to a decrease in the target image contrast). The developed compensation method for atmospheric attenuation of radiation in active electro-optical systems with dynamic spectral processing is based on the fact that the spectral intensity of the sensing radiation is formed not only on the basis of a priori data on spectral characteristics of the target and background, but also takes into account the spectral transmittance of the optical radiation propagation medium.","PeriodicalId":21598,"journal":{"name":"Semiconductor physics, quantum electronics and optoelectronics","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88204959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ideas, materials and structures of nanophysics have found their wide application in related fields of modern science, including biology and medicine. This short review is devoted to the application of nanophysics in modern medicine. The main focus was on application of ideas and physical phenomena of nanophysics in oncology and antiviral therapy. We have focused on the use of nanosystems both for tumor imaging and for the struggle against some types of tumors. The use of nanoparticles as nanocontainers for targeted drug delivery was briefly discussed. We also demonstrated how the effects of nanophysics can be used to develop new non-traditional methods of antiviral therapy. The focus of these methods was the idea of physical (field) action of nanoparticles on the viruses, which is based on the local-field enhancement effect that is the reason of ponderomotive forces acting on the viruses up to destruction of viral envelopes.","PeriodicalId":21598,"journal":{"name":"Semiconductor physics, quantum electronics and optoelectronics","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76826525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
