The present invention discloses nanomechanical fabrication methods of hybrid aligned nematic (HAN) cells of liquid crystals for creating analog spatial light modulators and smart pixel arrays on conventionally fabricated VLSI integrated circuits. The liquid crystal material is encapsulated between a top substrate and a bottom substrate. The locally averaged direction of the long axis of the molecules of liquid crystals of the HAN cells varies smoothly from homogeneous alignment on a top substrate to homeotropic alignment on a bottom substrate. The bottom substrate causes a homeotropic alignment of the liquid crystal because of its porous microstructure.
