The diffraction characteristics of a new type of alignment-controlled holographic polymer dispersed liquid crystal (AC-HPDLC) were studied, A very fine, 100-nm-scale, polymer region was formed holographically by keeping the LC helically aligned. The polarization dependence of ordinary AC-HPDLC was reduced due to the axial symmetry of the alignment. The induced modulation in the refractive index of the HPDLC when an electric field is applied interferes with the reflection of the helical structure. This coexistence of controlled and natural structures should achieve materials with higher functionality.
