Abstract
The invention concerns a saturable absorbent structure comprising a stack of layers forming a succession of quantum wells and barriers and a plurality of recombination centres distributed in said stack. The invention is characterised in that the recombination centres are made of a material such that they define with the materials of the stack one or several energy levels in the forbidden band of energy defined between the conduction band and the valence band of the wells of the stack.
