Which consequence results when excessively increasing power modulating the laser diode within fiber optic gyroscopes used for inertial navigation systems?

💡 Explanation

Increased power causes greater temperature gradients leading to index of refraction fluctuations. This induces non-reciprocal phase shifts via the Sagnac effect, because thermal GRADIENT DRIFT violates gyro accuracy standards; therefore, random walk error increases rather than improved error cancellation at higher powers.
