Abstract :
The AlGaAsSb system appears very suitable to elaborate high reflective DBRs with a low number of pairs operating at wavelengths of interest for telecommunications (1.3 and 1.55 /spl mu/m). Very high reflectivities of 99.2% at 1.56 /spl mu/m and for the first time 98.8% at 1.3 /spl mu/m have been obtained. We are now investigating this antimonide approach for fabricating monolithic VCSELs. Thus the elaboration of an active layer composed of InGaAs wells encapsulated within AlGaInAs barriers is under evaluation.
