Optical properties of GaN/AlN quantum dots under intense laser field

Abstract

We investigate the influence of intense laser field on the energy state and optical properties induced by sublevels transition of quantum dot. The quantum system includes the piezoelectric effect that rarely mentioned in related references. The linear, nonlinear and total optical properties for two cases with different quantum dot radius are examined. The peak positions and the peak amplitudes of spectra change drastically due to different size of quantum dot.
