Paper Abstract

Two kinds of optical fiber sensors that are fabricated with fiber side polishing technique are proposed and demonstrated experimentally to measure the concentration of acetic acid solution. One kind is side polished fiber Bragg grating (SPFBG) sensor, which is fabricated by side polishing the cladding over the grating region of fiber Bragg grating. The reflective Bragg wavelength of SPFBG sensor shifts when its polished region is overlaid with different concentration of acetic acid solution, so the concentration of acetic acid solution could be measured. Its resolution is 6.67%. The other kind is side polished fiber (SPF) sensor fabricated by single mode fiber whose part of cladding is side polished. The concentration of acetic acid could be measured by the transmitted optical power when polished region is overlaid with acetic acid solution. Its resolution of sensor is 0.55%.
