Abstract: A plurality of holes in a top surface of a silicon medium form a plurality of sub-meta lenses to result in multiple focal points rather than a single point (resulting from using a single meta lens). As a result, optical paths for incoming light are reduced as compared with a single optical path associated with a single meta lens, which in turn reduces angular response of incident photons. Thus, a pixel sensor including the plurality of sub-meta lenses experiences improved light focus and greater signal-to-noise ratio. Additionally, dimensions of the pixel sensor are reduced (particularly a height of the pixel sensor), which allows for greater miniaturization of an image sensor that includes the pixel sensor.
