Paper Abstract
We report the fabrication of a highly sensitive refractive-index sensor based on three cascaded single-mode fiber tapers,
in which a weak taper is sandwiched between the two tapers to improve the sensitivity of the sensor. Experimental
results show that the sensitivity of the device is 0.286 nm for a 0.01 RI change, which is about eleven times higher than
that of the normal two cascaded tapers MZ interferometer. Such kind of low-cost and highly sensitive fiber-optic
refractive index sensors will find applications in chemical or bio-chemical sensing fields.
