Shaping the topology of light from liquid crystals self-organization
Shaping the topology of light from liquid crystals self-organization
Liquid crystals underpin key optical technologies, especially displays, where their orientational order is precisely controlled. Beyond this, they can host diverse topological structures, both singular and non-singular, and exhibit strong sensitivity to broken symmetries across multiple scales, enabling agile self-engineered photonic systems. What began as observations of light scattering from defects has evolved into a framework where liquid crystal textures tailor optical field topology in a deterministic and reconfigurable way, which I will overview.
