An optical device. The optical device includes an underlying device that is sensitive to input light, and provides output light in a first spectrum based on absorbing the input light. The optical device further includes a stacked device, formed in an active area of a single semiconductor chip, coupled in an overlapping fashion to the underlying device. The stacked device includes first and second zones. Each zone has a plurality of active elements having a particular lateral size, where the lateral size is different for each zone. Each zone also has a plurality of transparent regions formed in the stacked device which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through from the underlying device. The transparent regions are configured in size and shape to cause each zone to have a particular transmission efficiency for light in the first spectrum
