Abstract

Analog optical matrix-vector multipliers (OMVMs) compute matrix-vector products rapidly due to the parallelism and high speed of optics. However, their low analog accuracy hinders their widespread application. Digital partitioning is a promising new technique for achieving high accuracy computations on analog OMVMs. One potential drawback of digital partitioning is its sensitivity to errors. The results presented here show how error-correcting codes can reduce this sensitivity to errors. Various computer simulation results are presented to show that a significant reduction of error can be obtained.
