Abstract :
A novel kind of all-optical dynamic grating with the reflectance and the center wavelength controlled by another optical wave can be realized based on Brillouin scattering in polarization-maintaining optical fibers. This grating, called Brillouin dynamic grating (BDG), has proved to be useful based on its unique characteristics in several applications such as high performance distributed sensors and optically-tunable delay lines.
