Abstract: An image sensing device includes a germanium sensor within a semiconductor body and a metalens formed in the back side of the semiconductor body. The metalens is structured to focus infrared light on the germanium sensor and may have a lower profile than an equivalent microlens. Optionally, the metalens is combined with a microlens to achieve a desired focal length.
