高兆兰讲座（第二十六期）（2025年11月3日15:00）：The promise of programmable optical metasurfaces

主持人：董建文教授

报告简介：Light projection displays have become integral to modern life, influencing applications from entertainment to communication and beyond. Core technologies such as liquid crystal displays and digital micromirror devices enable spatial light modulation, actively shaping light waves to create vivid and dynamic visuals. Recently, the advent of metasurfaces has introduced a paradigm shift in display design, offering unprecedented control over light propagation and unlocking new degrees of freedom. In particular, metasurfaces empower the realization of ultrathin, lightweight, and highly efficient optical devices, paving the way for transformative advancements in display technologies.

In this talk, we will explore the forefront of metasurface-based display systems, focusing on programmable metasurfaces designed for dynamic holographic displays. These systems demonstrate the ability to manipulate light at subwavelength scales, enabling precise control over amplitude, phase, and polarization. Furthermore, we will highlight recent breakthroughs in achieving single-pixel programmability and addressability in metasurface devices. By integrating innovative materials and electronic control mechanisms, these developments hold the potential to redefine spatial light modulation, opening new pathways for ultrahigh-resolution, compact, and energy-efficient projection systems.
