Abstract

We propose a simple distributed sensor with millimeter-order spatial resolution using a multichannel fiber Bragg grating (FBG). The multichannel FBG was designed by using the layer peeling (LP) algorithm with a tailored group delay characteristic, in which each channel is spatially separated. The multichannel FBG can be easily used in a low cost WDM sensing system for distributed sensing with millimeter-order spatial resolution.
