Abstract

Laterally inhibitive connections form a basic component of many neural network algorithms. This paper describes a self-linearised inhibitory test system (SLITS) to demonstrate basic image manipulation using arrays of quantum well (QW) modulators. Inhibition between neighbouring nodes is utilised to perform edge contrast enhancement [1]. System interconnections are both optical and electrical with non-local interconnections being made optically using diffractive elements and a one-to-one electronic connection providing the inhibitory response.
