Paper Abstract

A simple Fresnel reflection-based optic fiber refractometer for simultaneous multi-point refractive index measurement based on an Arrayed-Waveguide Grating (AWG) is proposed. Different channel lights divided by the AWG are marked with different central wavelengths and their Fresnel reflective lights from the fiber-solution interfaces are used to measure the refractive indies of the inserted different solutions at the same time. The refractive index sensitivity for each channel sensing head reaches up to 157.1dB/RIU.
