Abstract
In this communication, we report experimental results on optical injection of quantum dot (Q-dot) [1] and quantum dash (Q-dash) [2] semiconductor multi-mode lasers. We show the impact of a strong damping on optical injection map and reveal the observation of a random phenomenon of multi-excitability on such structure. These properties are obtained thanks to the different structural properties of Q-dash and Q-dot and by comparing Q-dash lasers having different numbers of Q-dash plans.
