本文讨论了多模光纤锥形化的理论和实验意义，以期将其用于倏逝波吸收光谱学。获得了良好的实验结果，表明吸收效率提高四倍的可能性。这种简单和可重复的锥形制造技术适用于光谱和化学辅助光纤传感器的探头的实施。
This paper discusses the theoretical and experimental implications of tapering a multimode optical fiber with a view to its use in evanescent wave absorption spectroscopy. Good experimental results are obtained, showing the possibility of quadruplicating the absorbance efficiency. This easy and reproducible technique for taper fabrication is suitable for the implementation of both probes for spectroscopy and chemically assisted fiber-optic sensors.
