The strong strain distribution induced in the bowed airbridge and the effect on the electronic states of the quantum dots (QD) were investigated. The strain distribution in and around the QD was calculated by the finite element method. The strain in the bowed airbridge to distribute from tensile to compressive along the growth direction was shown by the finite element calculation. The calculation demonstrated that the characteristic strain distribution around the dot embedded in the bowed airbridge modified not only the energy levels, but also the wave functions.
