文摘Using the simple treatments of back refilling and subsequent annealing above the clear point of the liquid crystal,the self ordering of liquid crystal molecules is observed in a holographic polymer dispersed liquid crystal (HPDLC)Bragg grating without orientational layers or mechanical rubbing.Transmittance curve fitted anisotropy of the liquid crystal (△n) is in good agreement with its nominal value.
