Abstract
An integrated circuit is formed in a semiconductor substrate. An array of single-photon-avalanche diodes is formed at a front side of the semiconductor substrate. The array includes first and second diodes that are adjacent to each other. A Bragg mirror is positioned between the first and second diodes. The Bragg mirror is configured to prevent a propagation of light between the first and second diodes.
