We have presented the results on GaSb-based tapered diode lasers with an emission wavelength of 1.91 /spl mu/m at 20/spl deg/C. The active layer of the samples consists of three compressively strained GaInSb - QWs, embedded in a broadened AlGaAsSb - waveguide structure. The lateral design is composed of a ridge-waveguide (RW) section followed by a trapezoidal amplifier. The width of both sections has been varied in order to study filamentation effects which have already been described in other material systems.
