← TechnologyWhich risk dramatically escalates when the **stimulated emission** within a fiber optic gyroscope degrades below threshold?
A)Signal fading becomes unpredictable
B)Interferometric drift rapidly increases✓
C)Chromatic dispersion is significantly enhanced
D)Polarization mode shifts occur
💡 Explanation
Interferometric drift increases due to diminished constructive interference between counter-propagating beams because decreasing stimulated emission affects phase measurement accuracy, therefore precise angular velocity measurement becomes unreliable, rather than simple signal loss.
