Strained InGaAs-GaAs quantum-well lasers by impurity-induced disordering with very low threshold and moderate blue-shift

The authors report on strained InGaAs-QW impurity-induced disordering (IID) lasers having self-aligned structure with very low threshold current and moderate blue-shift of the lasing wavelength. The strained InGaAs-QW material employed was grown by MOCVD. The fabrication process is described. The authors believe that IID by Si diffusion is a very attractive approach for the fabrication of strained InGaAs-QW lasers.
