The top-rated Laser & Photonics Reviews published a study from the cluster of the laboratories of Hybrid Photonic Nanomaterials and Nano-Bioengineering, NRNU MEPhI, on the induced transparency effect

The study Induced Transparency in Plasmon–Exciton Nanostructures for Sensing Applications by Victor A. Krivenkov, Semyon A. Goncharov, Igor R. Nabiev, and Yury P. Rakovich, of the cluster of international laboratories of Hybrid Photonic Nanomaterials (LPNM) and Nano-Bioengineering (LNBE) has been published in the Laser & Photonics Reviews, one of the world-leading journals on optics.

The study, directed by Yury P. Rakovich, professor of the University of the Basque Country (Spain), deals with induced transparency, a unique effect occurring when light–matter hybrid states arise in systems consisting of absorbers and plasmonic nanoparticles. The effect is expressed as a narrow transparency window precisely corresponding to the absorption energy in the extinction spectrum of plasmonic nanoscale objects. The main distinctive feature of the induced transparency in these hybrid nanosystems is the possibility of using noncoherent broad-band light sources, such as lamps, in contrast to the classical electromagnetically induced transparency, which occurs only in laser fields. Furthermore, the transparency windows may be observed not only for electron transitions in the visible spectral region, but also for vibrational and rotational transitions in the IR range, which offers the possibility of using this effect in designing sensors for various purposes. Having analyzed the data on induced transparency, its dependence on the geometry and composition of plasmonic nanostructures, parameters of molecular absorbers, and their mutual arrangement, the authors identified the key parameters determining the strength of this effect.

The conclusions drawn from the results will serve as the basis for developing sensors with a uniquely high sensitivity that could be used, e.g., for the detection of ultrasmall concentrations of various substances in the environment, as well as disease biomarkers and pathogens in laboratory medical diagnosis.

Laser & Photonics Reviews is a top-rated journal included in the first quartile (Q1), with an impact factor of 8.5, published by the Wiley-VCH. According to the Journal Citation Reports (JСR) ranking, it is the fourth among the best 94 world journals in the Optics category. The editors of the journal considered the paper from the cluster of NRNU MEPhI "Mega-laboratories" important enough to put its graphic abstract to the journal's cover.
