Abstract

In order to increase angular response or otherwise customize the response of phase detection pixels to incident light, phase detection pixels may include optical structures. The optical structures may be formed between a microlens and at least first and second photodiodes to redirect incident light between the microlens and the photodiodes. The optical structures may include two or more layers with different indices of refraction. For example, a layer of silicon dioxide and a layer of silicon nitride may form a concave lens that increases the angular response of phase detection pixels. The optical structures may have any desired shape to customize the response of the photodiodes to incident light.
