Abstract: A novel fiber grating tapered cavity sensor used for encoding strain into its spectral profile independently and its experimental demonstration are presented. The sensor possesses two spectral peaks within its main reflection band and the normalized power difference between the two peaks changes linearly with applied strain while it is independent of temperature variation. The accuracy of this particular sensor in measuring strain is estimated to be ±29 με in a range of ±1200 με.
