Paper Abstract

A new approach to refractive index sensing for biological solutions has been investigated for a web-based monitoring system. The system was implemented such that the refractive index was monitored by an LPG-FBG hybrid sensor. The point was how the enhanced sensitivity range of LPG could be used. For the purpose, equations were newly derived, based on a nonlinear relationship between values of the refractive index and the resonant wavelength. The values calculated by the equations were in good agreement with experimental values monitored by the system, enabling the system to use the enhanced sensitivity range.
