The working principle of surface Plasmon resonance (SPR) of a 2 × 2 tapered coupler is introduced. It was used to act as a liquid refractive--index sensor. The fabricated sensor is used to measure the refractive--index of Glycerol water within the range from 1. 448 to 1. 4515. The resonant wavelength of SPR is observed to shift from 1450 nm to 1593 nm. Linear relationship is shown between the wavelength and the index value. The system achieves a resolution of 2. 448 × 10-5RIU.
