Abstract

Complex spatio-temporal dynamics can be observed in single broad-area semiconductor lasers under external optical feedback. Yet, non-linear dynamics is mostly unexplored in large 1D-arrays of lasers. In our recent investigations, we demonstrated both numerically and experimentally that single-mode and broad-area laser arrays in a V-shape external cavity can generate complex spatio-temporal dynamics with typical frequencies in the GHz range as well as periodic and chaotic phase-locking. Feedback misalignment and feedback strength are key parameters to warrant that diode lasers in the array display a variety of dynamics. Potential applications may include directed energy, LIDAR, and random number generators.
