Accuracy Enhancement in Optical Computing.

Abstract

Investigations of techniques for describing and enhancing the accuracy of optical linear algebra processors have been conducted. Significant accomplishments include: (1) showing that error correcting codes can improve processor accuracy and developing criteria which such codes need to possess in order to be suitable for this task; (2) developing a system model incorporating device dynamic range for better quantitative assessment of error correcting code performance; (3) completing a detailed study of the combination of digital partitioning and Modified Multilevel Hamming Codes to achieve high accuracy computation, including scaling properties and effects on processor throughput.
