Multidimensional Light‐Field Modulation via Liquid Crystal Coherent Pixels for Simultaneous Near‐Field Nanoprinting and Far‐Field Color Holography

ABSTRACT Liquid crystals (LCs) have emerged as versatile optical platforms for constructing a wide range of imaging and display devices through flexible modulation of light parameters. However, most LC‐based elements suffer from limited information capacity, restricting simultaneous multi‐channel imaging in both near and far fields. Here, we propose a multidimensional light‐field multiplexing paradigm based on LC coherent pixels. By analytically resolving the coherent superposition of LC phase responses, precise and independent encoding of dual‐channel nanoprinting patterns is achieved in the near field. Beyond near‐field control, we further introduce an improved holographic optimization framework that co‐designs the near‐field intensity distribution and far‐field phase profile in a unified manner. By incorporating off‐axis illumination with red, green, and blue (RGB) light, the far‐field functionality is extended from monochromatic holography to full‐color imaging, while fully preserving near‐field nanoprinting performance. For the first time, we experimentally demonstrate the integration of near‐field dual‐channel pattern switching and far‐field full‐color holography within a single LC element. This work breaks through the conventional information‐channel limitations of LC optical devices and establishes a general strategy for high‐integration, low‐cost, and multifunctional light‐field modulation devices, opening new avenues for advanced applications in information encryption, virtual reality, and multifunctional display technologies.
