A refractive index (RI) sensor is proposed which consists of a combination of an intermodal photonic crystal fiber (PCF) interferometer as a sensing head and a fiber Bragg grating (FBG) as a demodulating element. The intermodal PCF interferometer is formed by using a short PCF which is spliced with...
