Abstract

A polarization sensitive solid state image sensor includes an integrated photodetector and polarizing assembly. The polarizing assembly is formed directly on an upper dielectric surface of the photodetector as a metal grid. The integral form of the device improves polarization operation and reduces manufacturing costs.
