| Abstract: | Optical sensing by using fiber is an attractive research area nowadays. Using optical sensing of fiber system can detecl the pressure, temperature, hltmidity and concentration in environment which would facilitate the connecting between things. In this paper, we suggest a refractive index sensor based on optical nano-fiber. The proposed optical sensor can detec! lhc local variation of the refractive index around the optical nano-fiber. We present the method to directly solve the electromagnetic problem which shows exactly the proposed nano - fiber geometry can be used as a probe for local refractive index. The mechanism underlying this phenomenon and the limitation of the detection limitation are also discussed. |
