A method, based on the thumbtack correlation properties of chaotic laser signal, is presented to induce permanently sustained, localized dynamic Brillouin gratings in polarization maintaining optical fibers. A numerical analysis of two possible experimental setups, all-optical and electro-optical, is performed. The possibility to apply the permanent grating in sensing is explored.

Abstract
A method, based on the thumbtack correlation properties of chaotic laser signal, is presented to induce permanently sustained, localized dynamic Brillouin gratings in polarization maintaining optical fibers. A numerical analysis of two possible experimental setups, all-optical and electro-optical, is performed. The possibility to apply the permanent grating in sensing is explored.
