摘要:
The critical findings associated with end-face total internal reflection (TIR) phenomemon we proved before are reported, In particular, these findings reveal that the end-face-TIR capable rays experience enormous mode mixing when encountering a roughened end face.As a result, 94Vo of the overall detectable poweris contributed by this effect.With a smooth fiber end face, this figure is mere 52%.We interpret the mechanism behind these unusual phenomena and its significance for the performance enhancement of fiber optic evanescent wave sensor.
