Abstract
High-frequency self-pulsing effects in combined index and gain coupled two-section DFB lasers in a single cavity laser are investigated by numerical simulations. The gain coupling increases the modulation index and frequency of the intensity oscillations. The results show that the signals of oscillation frequencies up to 200 GHz may be possible to generate using such devices.
