Holographic Interconnects for Optical Neural Networks

摘要

This research work focused on the development of diffractive optic interconnectelements (DOIEs), which are computer designed, e-beam fabricated holograms used for implementing free space optical interconnects. Accomplishments of the work included development of an improved hybrid design strategy for the design of phase only holograms, development of a versatile software package for hologram design and analysis, continued development and characterization of the e-beam fabrication technology, careful measurement of the performance achieved by fabicated holograms, and investigation of applications that utilize the technology. The applications included optical neural networks, which require analog weighted interconnects, and digital optical computers utilizing binary weighted interconnects. The software package for interconnect design, evaluation, and reconstruction (SPIDER) was written to run on Unix based computer platforms and is freely available over the Internet.
