Abstract:

The GaNAs strain compensation layers for the growth quality of the InAs/GaAs quantum dots stack in quantum dots verticalcavity surfaceemitting lasers (QDVCSELs) are investigated. The influences of different concentrations and locations of the compensation is obtained. The approach in determining the optimal compensation parameters is also achieved. We give instructions in fabricating the QD active region in QDVCSELs of long wavelength (12-16μm).

Key words: strain compensation, quantum dots, verticalcavity surfaceemitting lasers
