Abstract
A PIN photodiode structure uses direct side entry into the I region, thus permitting the use of thicker P and N regions with a comparatively thin I region without sacrificing speed and results in more constant spatial distribution upon carrier generation and longer wave length devices with conventional speeds or smaller devices at faster speeds, and may be integrated on the same chip with associated circuits.
