The main work can be summed up as follows: Firstly, we studied the thermal-field properties of VCSELs, and analyzed the influences of current spreading, material parameters and operating conditions on the temperature distributions. Secondly, we began with the electrode voltage and calculated the equipotential s distributions, compared the distributions of voltages and current densities in different depths of VCSELs, and then studied the influences of the oxide-confining region with different position or thickness, and the different sizes of the gain-guided aperture and emitting window on the distributions of the injected current density, carrier concentration and temperature in the active region. Thirdly, we realized the coupling of electricity, optical and thermal-fields, worked out the threshold voltage, calculated the distributions of the injected current density, carrier concentration and temperature under different offset voltages, and analyzed the impacts of temperature profile and carrier density on the refractive index, Fermi levels and optical-field. Finally, we gave the equipotential line distributions with considering N-DBR and double oxidized-confining regions, and analyzed theinfluences of N-DBR and double oxide-confining regions on the distributions of the current density, carrier concentration, temperature and optical-field.

Results:Part1: Mean serum EPO concentration of CRF patients showed significant lower than that of control. After transplantation, renal function recovered quickly while Hb level increased steadily in 37 patients with immediate graft function. Their EPO concentration increased significantly and double peaks of EPO level were obtained at day 4 and week 4. 4 cases in IGF suffered from post-transplant erythrocytosis. But their EPO concentration did not reach statistical significance. 5 cases developed delayed graft function, without EPO double peaks and their EPO concentrations showed signiffcant lower than that of IGF.
