Abstract
The first-order diffraction efficiency η1 of surface-stabilized ferroelectric liquid-crystal (SSFLC) phase gratings is calculated for device thicknesses in the range d = 1 to 5 μm and for pitches p of 5 to 20 μm assuming incident light at 633 nm. The peak value of η1 as a function of d has negligible dependence on the incoming polarization when p = 20 μm. For smaller pitch values the peak value of η1 decreases and becomes increasingly dependent on the orientation of the incoming polarization owing to the influence of the domain walls that occur between the SSFLC pixels.
