英文摘要	A new method of analyzing the chirp characteristics of directly modulated lasers and integrated laser-modulators is presented in this paper. phase-circuit has been introduced into the circuit model of distributed feedback (dfb) lasers in the analysis. therefore, the chirp characteristics of the device can be obtained by simulating the modified circuit model. the simulation results agree well with the published data. furthermore, this modified model is combined with the circuit model of electroabsorption (ea) modulators to simulate the chirp characteristics of the monolithic integration of a dfb laser and an ea modulator. the simulation is focused on the dependence of the frequency chirp of the integrated device on the isolation resistance between laser and modulator. much lower chirp can be seen in the integrated lightwave source compared to the directly modulated laser.
