JETP Letters to publish 2 papers from laboratories of Nano-Bioengineering and Hybrid Photonic Nanomaterials, NRNU MEPhI

Two papers from the cluster of international laboratories of Nano-Bioengineering (LNBE) and Hybrid Photonic Nanomaterials (LPNM) are to be published in the first this year's issues of JETP Letters, one of the most prestigious Russian physics journals.

The study Spectral and Spatial Characteristics of the Electromagnetic Field Modes in a Tunable Optical Microcavity Cell for Studying Light–Matter Hybrid States by Dmitry Dovzhenko, Ivan Vaskan, Konstantin Mochalov, Yury Rakovich, and Igor Nabiev (JETP Letters, 109 (1)) continues a series of LPNM and LNBE's research and developments in the effects of interactions between electromagnetic field and matter in the strong and weak coupling regimes and their practical implementations. The authors have analyzed the optical parameters of the device based on a tunable Fabry–Perot microcavity that they designed earlier. This development was described at our website last May. The device can be used to study light–matter interactions in both strong and weak coupling regimes for samples of practically any substance in the spectral range from UV to IR. The microcavity used there has advantageous of versatility, a small mode volume, and the possibility of gradually changing the Q-factor and mode volume when dealing with a single sample.

Analysis of the device's parameters and their possible variations has shown that minimization of the distance between the cavity's mirrors decreases the strength of coupling by more than an order of magnitude. This eases the requirements for the concentration of the molecules, as well as the value and orientation of their dipole moment in the analyzed ensemble, which extends the range of systems where strong coupling can occur. The possibility of gradually varying the mode volume and Q-factor over a wide range offers new opportunities for the analysis of intermediate states involved in the transition from the weak coupling regime to the strong coupling one.

The results of this study have implications for photonics, chemistry, and biological sensing, as well as the designing of coherent light sources.

The paper Optical Properties of Core/Multishell Quantum Dots by Pavel Linkov, Pavel Samokhvalov, Kirill Vokhmintcev, Maria Zvaigzne, Viktor Krivenkov, and Igor Nabiev, which we have already written about, will be published in the same volume of the JEPT Letters.

JETP Letters is the English version of the Russian journal Pis'na v ZhETF, one of the top-rated Russian physics journals.
