A silica microfiber sensor is proposed and demonstrated for detecting different concentration of glucose in adulterated honey samples. The output signal of pure and adulterated honey samples with different additions of glucose percentage were measured. Six different honey samples were adulterated with different percentage of glucose ranging from 1% to 6%. Amplified spontaneous emission (ASE) was used as the light source for the silica microfiber sensor. As the concentration of glucose in honey is varied from 1% to 6%, the output power of the sensor decreased linearly from 14 dBm to 6 dBm. The sensitivity of the sensor to the adulterated honey is 1.5 dB/ppm and the slope shows a good linearity of 97.14%. This study can be concluded that silica microfiber sensor has high potential to detect adulteration of glucose in honey. © 2017 American Scientific Publishers All rights reserved.
