Paper Abstract

We recently reported on a new fiber Bragg grating etched into the flat surface of a D-fiber and its potential use as a high temperature sensor. Since then we have investigated more in depth many of the characteristics that are unique due to the surface relief nature of the grating. In this paper we show that a surface relief fiber Bragg grating exhibits some significant advantages when compared to standard fiber Bragg gratings including: high temperature operation, polarization selectivity, and the ability for multi axis strain sensing. We also show the uniqueness of these gratings for bend sensing with two degrees of freedom.
