Abstract: Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.

Abstract: Waveguide based displays benefit from gratings which are capable of diffracting both S and P polarized light with high efficiency. While typical surface relief gratings (SRGs) diffract P polarized light efficiently, SRGs do not typically diffract S polarized light efficiently. One class of gratings that diffracts S polarized light with high efficiency is deep SRGs. One approach to producing deep SRGs is holographic polymer dispersed liquid crystal (HPDLC) gratings. In producing HPDLC gratings, a reactive monomer mixture is exposed to light in a polymerization process. Reactive monomer mixtures may include co-initiators and photo-initiator dyes. Co-initiators which include liquid amine synergist have been demonstrated to have advantageous results. Further, photo-initiator dyes with high extinction coefficients have demonstrated advantageous results.
