Novel In-Plane Semiconductor Lasers XIX.
Surface–trapped electromagnetic waves can be localized at a boundary between a semiconductor distributed Bragg reflector (DBR) and a homogeneous dielectric medium or air. These waves enable a novel class of both in–plane–emitting and vertically

Vertical-Cavity Surface-Emitting Lasers XXIV.
We report high-frequency polarization self‐modulation (PSM) in high speed vertical-cavity surface emitting lasers (VCSELs) connected to the stress-induced birefringence in oxide-confined aperture VCSELs. Polarization oscillations up to 45 GHz were

Vertical-Cavity Surface-Emitting Lasers XXIV, Feb 2020, San Francisco, United States. pp.15, ⟨10.1117/12.2543244⟩
New applications in sensing, automotive and on-board applications require vertical-cavity surface-emitting lasers (VCSELs) operating at high data rates up to very high ambient temperatures. We study temperature stability of the 850 nm Quantum-Dot (QD

HIGH-ENERGY PROCESSES IN CONDENSED MATTER (HEPCM 2020): Proceedings of the XXVII Conference on High-Energy Processes in Condensed Matter, dedicated to the 90th anniversary of the birth of RI Soloukhin.
Numerical simulation of thermophysical processes is carried out when the surface layer of a two-component metal (Fe-C) substrate is modified by refractory nanoscale particles when heated by a moving inductor in a non- stationary three-dimensional set
