Optical metasurface technology is capable of manipulating the amplitude, phase, polarization and frequency of light in unconventional ways and can be used in a variety of optical applications including holography, color printing, beam shaping and edge detection, polarization generation and detection, creation of terahertz waves and it also has rich application prospects in imaging, wave-front engineering, nonlinear optics, quantum information processing, etc. Optical Metasurface Technology Forum will be held in conjunction with LASER World of PHOTONICS CHINA 2025 to discuss superstructured optical surface technology.
