Efficient Fabrication of High Bit-Level Pancharatnam-Berry Diffractive Optical Elements (PB-DOE) by Using LCoS For Photoalignment

Abstract

PB-DOE for linear 2π 8-bit phase modulation with tunable diffraction efficiency was fabricated by using phase-only liquid crystal on silicon (LCoS) device for photoalignment of liquid crystals (LCs). Wide viewing angle holographic images were dis-played.
