Personal Interest in Doctoral Thesis Topic Most Important for Confidence in Successful Defence
A researcher at HSE University analysed data on 1,539 doctoral students from 161 Russian universities to identify which features of a thesis topic are associated with academic success and engagement. The most important factor was found to be personal interest in the research topic, which was associated with almost all key aspects of doctoral programme experience—from engaging with the academic supervisor to research activity and confidence about successfully defending the thesis. The findings have been published in Higher Education.

Spectral Composition of Radiation from Microlaser Coupled to Waveguide

Ch. 45. P. 112–113.
Fedosov I. S., Fominykh N., Kryzhanovskaya N., Makhov I., Moiseev E., Ivanov K., Zhukov A.

We investigate the spectral composition of radiation of microdisk lasers coupled with optical waveguides. We study output spectrum and light-current characteristic of the microlaser obtained from the output edge of the optical waveguide. The microlaser demonstrated single-mode emission in extended ranges of the injection current, up to 75 mA, that are alternated with pronounced mode hoping. Such behavior, which we attribute to the laser self-heating, results in numerous kinks in the light-current characteristic. Single mode emission is kept at the same resonant wavelength in the range of pumping currents as high as 25 mA.

Образцова А. А., Ivanov K., Moiseev E. et al., Journal of Physics D: Applied Physics 2026 Vol. 59 No. 30 P. 305103
We demonstrate a thermo-optically tunable microlaser based on an InGaAs/GaAs quantum-dot (QD) active region employing a deformed limaçon-shaped cavity. The asymmetric geometry effectively lifts the degeneracy of high-Q whispering-gallery modes, enabling single-mode lasing. A side-mode suppression ratio exceeds 25 dB over a wide current range. Under continuous-wave electrical pumping, the device achieves a peak output power ...

Analysis of factors determining the azimuthal and radial order of lasing mode in III–V quantum dot disk microlasers
Konstantin A. Ivanov, Alexey E. Zhukov, Eduard I. Moiseev et al., Journal of Applied Physics 2025 Vol. 138 No. 10 Article 103104
Microlasers supporting whispering gallery modes attract great interest because of their potential use in photonic integrated circuits: they have size just an order of magnitude larger than their emission wavelength and exhibit good thermal and dynamic properties. It is usually assumed that in disk microlasers a whispering gallery mode of the highest azimuthal order and ...

A quantum-dot microdisk was optically pumped by continuous-wave excitation with a level sufficient for the ground-state lasing. The microdisk was additionally illuminated with sub-ps pulses of various powers. It was found that there is a critical level of pulse power that determines the subsequent transient process of the microlaser. Depending on the level of the ...

Temperature evolution of two-state lasing in microdisk lasers with InAs/InGaAs quantum dots
Makhov I., Ivanov K., Moiseev E. et al., Nanomaterials 2023 Vol. 13 No. 5 Article 877
One-state and two-state lasing is investigated experimentally and through numerical simulation as a function of temperature in microdisk lasers with Stranski–Krastanow InAs/InGaAs/GaAs quantum dots. Near room temperature, the temperature-induced increment of the ground-state threshold current density is relatively weak and can be described by a characteristic temperature of about 150 K. At elevated temperatures, a faster (super-exponential) increase in ...
