Abstract

Presented are experimental results that demonstrate bipolar optical incremental update in an amorphous silicon/ferroelectric liquid crystal (PLC) optically addressed spatial light modulator. The results are understood in terms of charge compensation in the PLC producing a nonlinear capacitance behaviour. Describing the FLCin this way, the experimental results have been accurately modelled. Also, an optoelectronic neural network, in which this device is incorporated as an adaptable weight storage device, is described and experimentally demonstrated with parallel optical updating of the interconnection weights
