摘要：
An optically addressed liquid crystal spatial light modulator (SLM) with a photosensitive amorphous hydrogenated silicon carbide (a-SiC:H) layer has been studied using holographic techniques. The maximum diffraction efficiency (DE) of the device amounted to ηmax = 50.5%. A decrease in the DE to a level of 0.5ηmax was observed at a spatial frequency of 75 mm−1. The high resolution and DE of the proposed SLM are due to features in the formation of an asymmetric grating line profile in the given structure.
