Optically Controlled Coherent Backscattering from a Water Suspension of Positive Uniaxial Microcrystals

  • Coherent backscattering of light from a water suspension of zirconium silicate microcrystals is experimentally studied. Optically controlled weak localization of photons is realized, which is due to the reorientation behaviors of positive uniaxial microcrystals induced by a linearly polarized pump beam. Because zirconium silicate particles are positive uniaxial microcrystals, their reorientation behaviors are contrary to negative ones. Our work widely extends the materials used in the light-controllable weak localization of photons.
