quantum-well laser - traduction vers russe

OPTICAL INSTRUMENT
QC laser; Quantum cascade lasers; Quantum Cascade Laser; Fabry–Perot laser; Quantum cascade laser
  • Subband populations are determined by the intersubband scattering rates and the injection/extraction current.
  • In quantum cascade structures, electrons undergo intersubband transitions and photons are emitted. The electrons tunnel to the next period of the structure and the process repeats.
  • Interband transitions in conventional semiconductor lasers emit a single photon.
  • Electron wave functions are repeated in each period of a three quantum well QCL active region. The upper laser level is shown in bold.
  • Schematic of QC device in external cavity with frequency selective optical feedback provided by diffraction grating in Littrow configuration.
  • End view of QC facet with buried heterostructure waveguide. Darker gray: InP, lighter gray: QC layers, black: dielectric. Heterostructure ~ 10 um wide
  • End view of QC facet with ridge waveguide. Darker gray: InP, lighter gray: QC layers, black: dielectric, gold: Au coating. Ridge ~ 10 um wide.

Quantum-cascade laser

Quantum-cascade lasers (QCLs) are semiconductor lasers that emit in the mid- to far-infrared portion of the electromagnetic spectrum and were first demonstrated by Jérôme Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson, and Alfred Cho at Bell Laboratories in 1994.

Unlike typical interband semiconductor lasers that emit electromagnetic radiation through the recombination of electron–hole pairs across the material band gap, QCLs are unipolar, and laser emission is achieved through the use of intersubband transitions in a repeated stack of semiconductor multiple quantum well heterostructures, an idea first proposed in the article "Possibility of amplification of electromagnetic waves in a semiconductor with a superlattice" by R. F. Kazarinov and R. A. Suris in 1971.
