摘要：
Saturable absorber based on GaInAS/InP multi-quantum well structures are studied. Iron doping is used to control their absorption recovery time from ns down to sub ps regime reaching a record value of 0.29 ps. However at high doping level (10(19) cm(-3)) and sub ps regime, the non-linear amplitude variation is reduced by Fe-exciton interaction.
