Abstract

DFB laser integrated with external MZ modulator is an excellent candidate for long haul fiber optical communication systems with modulation speed beyond 10 GBits/s. An understanding of the behavior of the adiabatic chirp is required for device optimization. Adiabatic frequency chirps under various conditions are calculated based on a model in which the influence of the reflection from MZ modulator to the monolithically integrated DFB laser is considered. For a given modulator structure, the results show that adiabatic frequency chirp can be reduced by a proper choice of DFB laser parameters.
