Which instability results when reflections within an optical fiber constructively interfere?

💡 Explanation

Stimulated Brillouin scattering experiences amplification because backward-propagating photons from reflections undergo constructive interference, which increases acoustic phonon density in the fiber; therefore, SBS becomes pronounced, rather than bandwidth or thermal effects, increasing threshold limits.
