Les nanolasers [PDF]

Reflets de la physique, 2010
Lorsque les dimensions des lasers deviennent submicroniques, la physique qui gouverne leur fonctionnement est modifiee : les effets quantiques sont alors preponderants et le role joue par l’emission spontanee devient tres important, non seulement au passage du seuil, mais aussi en regime d’emission stimulee.
