Description:

Liquid crystal Pancharatnam-Berry optical elements (PBOEs) enable compact, efficient augmented and virtual reality displays but face chromatic aberration challenges. We propose a multi-twist narrowband PBOE structure to mitigate color crosstalk as validated by both experiment and simulation. Our approach significantly suppresses the chromatic aberration, offering design flexibility for RGB laser and quantum dot light sources.
