We explore the concept of passive-feedback lasers for direct signal
modulation at 40 Gbit/s. Based on numerical simulation and bifurcation
analysis, we explain the main mechanisms in these devices which are crucial
for modulation at high speed. The predicted effects are demonstrated
experimentally by means of correspondingly designed devices. In particular a
significant improvement of the modulation bandwidth at low injection currents
can be demonstrated.
