1. A transparent optical device configured to be used with an underlying device, the underlying device configured to emit output light in a first spectrum, the transparent optical device configured to transmit light in the first spectrum from the underlying device through the transparent optical device, the transparent optical device comprising:
an active area of a single semiconductor chip, configured to be coupled in an overlapping fashion to the underlying device, the active area comprising:
a first zone comprising:
a first plurality of active elements; and
a first plurality of transparent regions formed in the first zone 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 first plurality of transparent regions being configured in size and shape to cause the first zone to have a first transmission efficiency for light in the first spectrum; and
a second zone comprising:
a second plurality of active elements;
a second plurality of transparent regions formed in the second zone which are transparent to the light in the first spectrum to allow light in the first spectrum to pass through to the underlying device, the second plurality of transparent regions being configured in size and shape to cause the second zone to have a second transmission efficiency for light in the first spectrum, the second transmission efficiency being different than the first transmission efficiency; and
wherein the first and second zones are included in a plurality of zones with differing transmission efficiencies to create a gradient of transmission efficiencies.
