← ScienceWhich outcome occurs when imperfections introduce multiple wave paths in integrated silica waveguides?
A)Interference increases pulse broadening✓
B)Chromatic dispersion decreases bandwidth
C)Refraction eliminates signal leakage
D)Polarization stabilizes optical amplification
💡 Explanation
Interference increases pulse broadening from differing path lengths because modal dispersion spreads the pulse in time, therefore shorter links are necessary, rather than alternatives where impairments cause distinct signal degradations.
