Research Abstract

The purpose of this work is to develop a high efficiency quantum dots(QDs) laser, utilizing a subband formation with tunnel effect between the multi staked QDs structures. In this work, we have calculated the coupling of wave-function various barrier widths in QDs and the wave function have been coupled under 10nm barrier width. Through the calculation and experiments, it was shown that the Optical amplification factor was highest level in the multi stacked QD with as 3.5nm barrier width.
