Abstract :
Quantum dots emitting in the 1.3 /spl mu/m wavelength region can be realized following the dots in a well (DWELL) concept. By optimization of growth parameters as e.g. the V/III ratio and the design of the dot layers we could achieve a significant improvement of the dot characteristics as well as of the laser performance.
