Mid-infrared analogue polaritonic reversed Cherenkov radiation in natural anisotropic crystals

Nature Communications, 2023
Cherenkov radiation (CR) excited by fast charges can serve as on-chip light sources with a nanoscale footprint and broad frequency range. The reversed CR, which usually occurs in media with the negative refractive index or negative group-velocity ...

Silicon Microspheres for Super‐Planckian Light Sources in the Mid Infrared

Advanced Optical Materials, 2023
AbstractSilicon microspheres with a diameter in the range of 2–3 micrometers constitute photonic nanocavities that emit light through their Mie resonances when heated at high temperatures. At 500–600 °C these microresonators show a particular mid‐infrared (MIR) emission dominated by the lowest order modes.

Comparative Modeling of Infrared Fiber Lasers

Photonics, 2018
The modeling and design of fiber lasers facilitate the process of their practical realization. Of particular interest during the last few years is the development of lanthanide ion-doped fiber lasers that operate at wavelengths exceeding 2000 nm.
