← ScienceWhich signal degradation occurs because of Fresnel Rhomb misalignment?
A)Increased insertion loss✓
B)Chromatic dispersion offset
C)Reduced group velocity
D)Enhanced stimulated emission
💡 Explanation
Increased insertion loss results from inexact angular correspondence between input and output polarized light, because polarization rotation is the mechanism driving this. Therefore insertion losses occur, rather than modified dispersion, because the rhomb's internal reflections become imperfect under angular stress.
