Patent 11075314 was granted and assigned to Hewlett Packard Enterprise on July, 2021 by the United States Patent and Trademark Office.
An example device includes a doped absorption region to receive optical energy and generate free electrons from the received optical energy. The example device also includes a doped charge region to increase an electric field. The example device also includes an intrinsic multiplication region to generate additional free electrons from impact ionization of the generated free electrons. The example device includes a doped contact region to conduct the free electrons and the additional free electrons.
