We present a study of the frequency of occurrence of quasi-periodic fluctuations (QPFs) of microwave
radiation from solar active regions at the pre-flare stage. We used correlation curves obtained with the
Nobeyama Radioheliograph (NoRH). We analyzed 529 flares of classes X, M, and C (according to the GOES
classification). In a significant number of considered events (approximately 75% ...

We report on InGaAs/GaAs quantum dot injection microdisk lasers laterally connected with a bus waveguide fabricated by planar technology from the same epi-structure. Various coupling schemes of microlaser with waveguide are studied including a microlaser attached to a waveguide (zero gap), a 100 nm gap for evanescence light outcoupling, and with a waveguide surrounding the ...

Semiconductor lasers have developed rapidly with the steady growth of the global laser
market. The use of semiconductor laser diodes is currently considered to be the most advanced
option for achieving the optimal combination of efficiency, energy consumption, and cost parameters
of high-power solid-state and fiber lasers. In this work, an approach for optical mode engineering
in planar waveguides ...

The dynamics of the preflare phase of microwave and ultraviolet emission for M-class X-ray flares in three active regions (ARs), two flares with coronal mass ejections (CMEs) and one flare without a CME, were considered. Extrapolation of the magnetic field in the AR corona showed that eruptive events were associated with the formation of a ...

We present a study of the spatial distribution of quasi-periodic oscillations (QPOs) of microwave emission in three solar active regions before flares. The following events are considered: SOL2011-09-06T01:50M5.3, SOL2011-09-25T02:33M4.4, and SOL2012-07-08T04:19C6.6. Daily observations on the Nobeyama Radioheliograph at a frequency of 17 GHz are used. In all three cases, pre-flare trains of the QPOs of ...

Using numerical simulation, the search for designs of asymmetric barrier layers (ABLs) in a laser
diode with a GaAs waveguide emitting at a wavelength of λ = 980 nm is carried out. A pair of ABLs adjoining
the active region on both sides blocks undesired charge-carrier flows and suppresses parasitic spontaneous
recombination in the waveguide layers. Optimal designs ...

To date, observational signs that determine the ability of solar active region to cause an eruption of matter into the high layers of the solar corona (CME) are not entirely clear. This makes it difficult to understand the physical mechanism of the CME trigger. This paper presents a search for observational signs that may indicate ...

Features of the implementation of a beam-pulse amplifier (BPA) of whistler waves in magnetospheriс
enhanced and depleted ducts with refraction reflection are considered. Extended along the magnetic
field, ducts with a width of about 100–300 km often occur after magnetic disturbances in the morning and
daytime magnetospheres beyond the plasmapause, where the excitation of chorus emissions occurs under ...

In this study, a comparative analysis was carried out on the preflare and flare conditions for six flares accompanied by coronal mass ejections (CMEs) and five events not accompanied by CMEs. All of the events occurred in the period 2011–2014. The features of the spatial dynamics of microwave emission of active regions (data from the ...
