Abstract

A simple sensor is proposed and demonstrated using a silica tapered fiber for sensing different concentration of potassium in de-ionized water. The tapered fiber is fabricated using a flame brushing technique to achieve a waist diameter and length of 10 μm and 80 mm, respectively. For a concentration change from 0 to 50 , the ouput signal of the sensor decreases exponentially from-10.04 dBm to-11.11 dBm with linearity of more than 92. The increment of potassium concentration increases the refractive index of the solution, which in turn reduces the index difference between core and cladding of the tapered fiber and thus allows more light to be leaked out from the fiber. This new potassium monitoring system provides numerous advantages such as simplicity of design and low cost of production. © 2015 SPIE.
