We present a complete large-signal dynamic model of electroabsorption modul
ator integrated (EAMI) distributed feedback (DFB) lasers using the time-dep
endent transfer matrix method, With this model, it is possible to analyze d
ynamic characteristics depending on optical feedback and spatial hole burni
ng. Also, we can separately calculate the laser and modulator chirp includi
ng the voltage-dependent modulator chirp parameter, the grating phase at th
e end of the laser section, the length of the waveguide region, and electri
cal coupling. Therefore, our model can provide better predictions regarding
the laser and modulator chirp, The calculated large-signal chirp using our
model has similar characteristics to the measured large-signal chirp for 1
0-Gb/s EAMI-DFB lasers.
