← ScienceWhich risk increases when photonic crystal fiber's periodicity degrades?
A)Increased stimulated Brillouin scattering
B)Lower-order mode confinement loss✓
C)Enhanced four-wave mixing efficiency
D)Reduced group velocity dispersion
💡 Explanation
Degraded periodicity disrupts the photonic band gap because it alters light guidance via Bragg scattering, causing light to leak from designed pathways; therefore, confinement in lower-order modes weakens, rather than enhanced scattering or modified dispersion, which necessitate fine-tuned fiber structure.
