Abstract

An imaging device may include single-photon avalanche diodes (SPADs). The single-photon avalanche diodes may be arranged in a one-dimensional or two-dimensional array in a SPAD-based semiconductor device. The SPAD-based semiconductor device may also include a transparent cover glass that is formed over the array of SPADs. Each line of SPADs within the SPAD-based semiconductor device may be covered by a respective light spreading lens. The light spreading lens may be formed as a groove in an upper surface of the transparent cover glass. The light spreading lens may have a uniform cross-section along its length. The light spreading lens may be formed as a convex lens on an upper or lower surface of the transparent cover glass.
