Abstract
A polarization recycling backlight and a multiview display employ a polarization-selective scattering feature configured to preferentially scatter out a first polarization component of guided light and a polarization conversion structure configured to convert a portion of a second polarization component of the guided light into the first polarization component. The polarization conversion structure includes a subwavelength grating.
