Conversion of circularly polarized light into linearly
polarized light in anisotropic phase gratings using photocrosslinkable
polymer liquid crystals, H. Ono, M. Nakamura and N. Kawatsuki, Appl. Phys.

The polarization state of the diffraction light from
the polarization holographic grating on varying the polarization
conditions of the writing beams has been investigated on the basis of
Jones theory. The authors found that the polarization holographic grating,
which was fabricated by irradiating the two writing beams with around 0.2
of polarization ellipticity, could convert circularly polarized light into
linearly polarized light, and the anisotropic phase grating under
above-mentioned condition was really fabricated using the
photo-cross-linkable polymer liquid crystal. This function, not observed
in the conventional polarization gratings, should be widely applied as
highly functionalized optical devices.
