Optimal Value

The rate equations are used to analyze the characteristics of a tandem consisting of a laser diode and a semiconductor optical amplifier made of a single heterostructure with quantum dots. The optimal value of the current distribution coefficient the amplifier and the laser, as well as the optimal resonator length that provides the highest output power of the tandem were determined. It is shown that the use of the tandem allows, at the same total consumed current, to significantly (more than 4 times for 1 A) increase the power emitted through the ground-state optical transition in comparison with that achievable with a laser diode solely being limited by the onset of lasing through an excited-state optical transition.

Power Characteristics

It is an expedient and efficient method to simulate the output power characteristics of a laser diode through the numerical analysis. In this paper, firstly, based on the rate equations of the electrons transition in the active layer, the functions of some key parameters, such as internal quantum efficiency, threshold current and leakage current, etc., are defined with the variance of working temperature. And an accurate numerical analytical model is built by adopting the low-complexity difference method. Then, the simulated results are compared with the results from testing and Optiwave3.0 software. The results show that, by using the proposed analytical model, the simulation on the output power characteristics of a laser diode can be realized in all input current fields, which overcomes the drawbacks within the Optiwave3.0 software. At the same time, the mean deviation between the simulated results and testing results is reduced obviously, and the average error is only 3.88%.
