On June 4, amidst the growing need for precision in photonic control across various domains such as optical imaging, communications, computing, and encryption, traditional liquid crystal devices, despite their capability to adjust phase and polarization under fixed inputs, face limitations due to factors like the axial geometry of liquid crystal molecules, retardation values, and absolute phases. These constraints hinder their ability to meet the real-time control demands of dynamic and complex optical fields. In fields like engineering, materials science, and biomedical imaging, the flexible manipulation of structured light, as well as the precise synthesis and measurement of vector beams, holds significant importance and urgently necessitates novel technological advancements.
