Abstract
There is disclosed herein a liquid crystal on silicon spatial light modulator, “LCoS SLM”, device arranged for in-plane switching. The LCoS SLM device comprises: a silicon backplane (1501); a transparent substrate (1581); a liquid crystal layer (1571); an electrode structure (1505, 1507) and a reflective component (1561, 1551). The liquid crystal layer (1571) is interposed between the silicon backplane (1501) and the transparent substrate (1581). The electrode structure (1505, 1507) is formed on the silicon backplane (1501) for generating an electric field in the liquid crystal layer (1571). The electric field is substantially parallel to the silicon backplane (1501). The reflective component (1551, 1561) is opposing the transparent substrate (1581).
