← ScienceWhich outcome is minimized in optical fiber when high coherence lasers propagate?
A)Speckle noise and modal interference✓
B)Chromatic and polarization dispersion
C)Brillouin and raman scattering losses
D)Fresnel reflection and interface losses
💡 Explanation
Spatially coherent lasers in fibers produce speckle because of modal interference. The uniform wavefront promotes this interference, therefore speckle noise is emphasized rather than suppressed, unlike with incoherent sources that would have less distinctive interference patterns.
