Abstract
A ratiometric wavelength measurement system based on a fiber bend loss edge filter has been proposed and demonstrated previously. Such a system offers the advantage of a high resolution, simplicity and a high measurement speed. The applications of such a system for the demodulation of the outputs of multiple Fiber Bragg grating (FBG) sensors requires the use of a high speed tunable filter to separate responses from multiple sensors. Here we present the results of modelling and analysis for a discretely tunable ferroelectric liquid crystal filter, which could be used as a channel dropper in a WDM-based demodulation system containing multiple FBG sensors.
