非線性半導體雷射之運算

Abstract

The conventional linear optical model, which was used to describe the lasing behavior, neglects the effects of spontaneous emission and defines the threshold condition intuitively. The defficiency of this model is unable to explain the experimental results. Here, a nonlinear model which takes the effect of spontaneous emission into account was solved by self-consistent method. It has been found that this model is able to illustrate several lasing characteristics which cannot be explained by linear optical model.
