Abstract

Static and dynamic frequency chirps in a typical lambda /4-shifted MQW DFB laser integrated with an external modulator are simulated by a newly developed DFB laser simulator. Their dependences on various important waveguide and material parameters, such as coupling coefficient, cavity length, dispersive round-trip phase in the external cavity, random facet phase and power reflectivity, linewidth enchancement factor in both the laser and modulator sections, as well as the laser bias current, are investigated systematically. Salient features of the frequency chirps in integrated devices are discussed in the presence of spatial-hole-burning in DFB lasers.
