Abstract 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 (Δn) is in good agreement with its nominal value.
