Aiming at their implementation in 1.55 μm laser structures thermal stability of the QDs during growth of the upper cladding layer was found to be a severe problem most probably due to movement of growth constituents resulting in a marked blue-shift of the emission. This shift was systematically investigated using thermal treatment to simulate cladding growth. The strong dependence of the blue-shift on growth temperature (T<sub>g</sub>) of the QDs is believed to be due to defects being incorporated during GalnAsP matrix deposition. The cause for the defects is assumed to be incomplete decomposition of the PH<sub>3</sub> or reduced surface diffusion length at low T<sub>g</sub> which support interdiffusion. Above T<sub>g</sub> = 510°C stable emission from the QDs independent of regrowth temperature in this range was observed.
