Abstract :
We propose and realize GaAs-based monolithic fast saturable absorber devices. The saturable absorber material developed is a group of GaInNAsSb quantum-wells that allow absorption at telecommunication wavelength. The quantum-wells are embedded in a Fabry-Perot microcavity. Two types of microcavity mirrors are studied : a high 1.83 index contrast GaAs/AlOx Bragg reflector and a 0.48 index contrast GaAs/AlAs Bragg reflector. We compare thermal resistivity measurements made on both microcavity types and describe their nonlinear and dynamic performances, for a potential application as all-optical reshaping regenerators in high bit-rate transmission lines
