Abstract
- For the first time to the best of our knowledge, we report an ethanol vapor sensor based on etched fiber Bragg gratings (FBGs) written into step-index polymer optical fibers (POFs). The end of POF with grating was etched by immersion in a mixture of acetone and methanol (ratio 2:1). The etching rate was computed equal to 3.44 µm/minute. Then, the etched FBG was exposed to ethanol vapors mixed with dry air in different concentrations at room temperature. The sensitivity of this sensor is equal to 56 pm/% of ethanol vapor concentration. [ABSTRACT FROM AUTHOR]
