Figure 1

Structure of phase-only LCOS devices, consisting of transparent top substrate with transparent ITO electrodes, alignment layers, LC material, glue seal, spacers (a gap supported by a single layer of spacers to control the thickness of the LC layer), aluminum reflective electrodes (pixel arrays) and a functional CMOS silicon backplane. CMOS, complementary metal oxide semiconductor; ITO, indium tin oxide; LC, liquid crystal; LCOS, liquid crystal on silicon.
