Abstract |
A new method of analyzing the chirp characteristics and self-heating effect for MQW laser is presented in this paper. With rate equations of MQW laser and thermal equation, this model allows the calculation of the electrical, optical and thermal interactions. With considering the threshold current as a function of temperature, we are able to analyze separately the effects of diode thermal resistance, series resistance, turn on voltage, characteristic temperature and well number on the chirp and self-heating parameter. We have shown when self-heating occurs in the laser, the chirp effect is increased. |
