A surface-stabilized ferroelectric liquid crystal (SSFLC) film, doped with a small amount of monomer, BAB-6, was fabricated. The alignment performance and electrooptical effect of SSFLC films polymerized under different polarities of the DC field were examined. A grating was then fabricated by curing a doped SSFLC cell with UV through a photomask. The grating thus formed was found to be a combination of a phase grating and an amplitude grating, between which the grating could be switched by applying a suitable voltage. The response time was in the order of 500–600 µs.
