Abstract

A large-signal dynamic model of electro-absorption modulator integrated (EAMI) distributed feedback (DFB) lasers are proposed. The time-dependent transfer matrix method is used. Large signal chirp and the optical pulse shape depending on the driving voltage, optical feedback, electrical coupling, grating phase at the end of the laser section, and length of the waveguide region are studied. Because we separately calculate the laser chirp and the modulator chirp to obtain accurate estimates, our model can accurately predict the laser and modulator chirp. The model can fit very well the large signal chirp measured for 10-Gbps EAMI-DFB lasers.
