摘要

制作了一种单模锥形光纤，用于DNA分子的测量，并监测其周围折射率的变化。纤维最细的尺寸大约是$\mathbf{8\ \mu m}$。在1342 nm/RIU的灵敏度下，通过观察透射光谱倾角的变化，给出了折射率变化的表达式。该传感器具有携带方便、抗电磁干扰、制造周期短等优点，具有广阔的应用前景。

Tapered Fiber Based Infrared DNA Molecule Sensor

A single mode tapered fiber is fabricated for the measurement of DNA molecule with monitoring the surrounding refractive index changes. The slimmest dimension of the fiber is roughly $\mathbf{8\ \mu m}$. Refractive index change was given an expression by observing the shifting of transmission spectrum dip with a sensitivity about 1342 nm/RIU. Such a sensor owns the superiorities of easy carrying, anti-electromagnetic interference and short manufacturing cycle, which would have a wide application prospect.
