Abstract

We present experimental data on the dynamic response to direct current modulation of off-the-shelf laser diode devices. We have been able to observe strong effects due to the light reflected at the fiber end, thus providing optical feedback. These effects are shown to have a major impact when the laser is close to a dynamical instability (period doubling bifurcation). We observe that around the frequency of resonance, the spectrum becomes periodic having several peaks spaced by the inverse of the external cavity round trip delay. A strong current modulation causes the laser diode to narrow this spectrum.
