Which consequence results when back-reflections overload laser diodes?

💡 Explanation

Mode hopping arises because optical feedback causes instabilities; this phenomenon is Longitudinal Mode Competition. This boosts one specific longitudinal mode, therefore leading to rapid shifts in the dominant mode rather than stable laser output.
