Abstract :
This talk focuses on experiments with lasers where the optical feedback is given by semiconductor sections without a grating. This situation was intensively studied theoretically, originally by Tager and Petermann who predicted very fast self-pulsations. Recently, the Institute´s cooperation partners at WIAS have created comprehensive bifurcation diagrams, which help the experimentalist to prepare and control the desired laser dynamics. In addition, their simulation tool LDSL is used to understand the impact of effects such as spontaneous emission noise, longitudinal spatial hole burning and nonlinear gain saturation, all of which are present in fabricated devices.
