Abstract

Intersubband relaxation time for InλGa1-xAs/AIAs multiple quantum wells presenting a large transition energy (680 meV) is measured by means of pump and probe experiments. Differential transmission decays in about 10 ps. The possible influence of intrasubband relaxation and Γ-X coupling on intersubband decay is discussed.
