中文摘要	in this paper, a mini-staged multi-stacked quantum cascade laser structure with a designed wavelength of 4.7 mu m is presented. by introducing five 0.5 mu m thick high thermal conductivity inp interbuffer layers, the 60-stages active region core of the quantum cascade laser is divided into six equal parts. based on simulation, this kind of quantum cascade laser with a 10 mu m ridge width gives nearly circular two-dimensional far-field distribution (fwhm = 32.8 degrees x 29 degrees) and good beam quality parameters m-2 = 1.32 x 1.31 in the fast axis (growth direction) and the slow axis (lateral direction). due to the enhancement of lateral heat extraction through the interbuffer layers, compared to the conventional structure, a decrease of about 5-6% for the maximum temperature in the active region core of the mini-staged multi-stacked quantum cascade laser with indium-surrounded and gold-electroplated packaging profiles is obtained at all possible dissipated electrical power levels.
