摘要:
In this paper, a novel liquid refractive index(RI) sensor based on fused tapered photonic crystal fiber(PCF) is proposed. It is fabricated by fusing and tapering a section of PCF which is spliced with two single-mode fibers(SMFs). Due to the fused biconical taper method, the sensor becomes longer and thinner, to make the change of the outside RI has more direct effects on the internal optical field of the PCF, which finally enhances the sensitivity of this sensor. Experimental results show that the transmission spectra of the sensor are red-shifted obviously with the increase of RI. The longer the tapered region of the sensor, the higher the sensitivity is. This sensor has the advantages of simple structure, easy fabrication, high performance and so on, so it has potential applications in RI measurement.
