摘要：
We have proposed a new model of the rate equation for laser diode performance analysis. A modulated signal of LD is analyzed by the rate equation using the finite difference method (FDM) in time domain. For the analysis of modulated optical signal, an injection current term in the rate equation is altered to an appropriated electrical function. L-I curve, intensity modulation frequency response, and nonlinearity of laser diodes are analyzed by the proposed rate equation model. The proposed model can be applied to determine the operating point of LD and to design the analog optical transmitter.
