Paper Abstract

Based on the condition of eigenmode self-consistency, the physical model of the fast light enhanced in ring resonator has been established, and the sensitivity enhancement factor of the fast light enhanced laser gyroscope is defined with the concept of group delay. Combining with the Taylor series expansion, the expression of group delay is derived and the dependence of the group delay and output frequency difference on the Gaussian beam divergence angle in the total reflection prism ring resonator is revealed. Furthermore, the influence of prism size on group delay and output frequency difference is also analyzed.
