Polymerized liquid crystal layers for transmissive and reflective diffractive components by printing. Ghent University
Diffractive optical elements with high efficiency can be used for extended reality displays or switchable optical interconnects. The combination of liquid crystals with patterned photoalignment makes it possible to define structures with the required optical functionalities in an accessible and effective way. A very high optical efficiency can be obtained with these kind of micrometer thin flat optical components. Through a polymerization ...
