Abstract

Preliminary attempts at aligning nematic liquid crystals using windows having sub-wavelength surface gratings show that good planar aligned cells can be fabricated. We also demonstrate all-optical nonlinear diffraction effect using methyl-red doped nematic liquid crystal that possess a large intensity refractive index change coefficient.
