Abstract
An image sensor includes a group of sensor units and a color filter layer disposed within the group of sensor units. The image sensor further includes a dielectric structure and a plurality of polarization splitters disposed corresponding to the color filter layer. Each of the plurality of polarization splitters has a first meta element extending in a first direction from top view and a second meta element extending in a second direction from top view. The second direction is perpendicular to the first direction.
