Photopolymerizable materials and in particular holographic polymer dispersed liquid crystal materials and processes for fabricating holographic waveguide devices from such materials are provided. Materials and formulations of photopolymerizable materials incorporate a mixture of LCs and monomer (and other components including: photoinitiator dye, coinitiators, surfactant), which under holographic exposure undergo phase separation to provide a grating in which at least one of the LCs and at least one of the monomers forms a first HPDLC morphology that provides a P polarization response and at least one of the LCs and at least one of the monomers forms a second HPDLC morphology that provides a S polarization response. |
