Described herein are the materials, mechanisms and procedures for optimizing various performance parameters of HPDLC optical devices in order to meet differing performance requirements. These optimization tailoring techniques include control and independent optimization of switchable HPDLC optical devices to meet the demanding requirements of anticipated applications for, inter alia, the
telecommunications and display industries. These techniques include optimization of
diffraction efficiency, i.e., index modulation, polarization dependence control,
haze, cosmetic quality, control of response and relaxation time,
voltage driving for on and off switching, and material uniformity. This control and independent optimization tailors properties of switchable HPDLC optical devices according to the specific requirements of the application of the switchable HPDLC optical device. The invention disclosed herein retains the desirable attributes of the multi-functional
acrylate system for forming HPDLC optical devices, but adds
new materials to the
acrylate system and / or new
process control to the recording to optimize performance parameters as may be needed for specific applications. This results in high
optical quality switchable holograms with good
diffraction efficiency and low, stable switching
voltage.
