Scientists from ITMO University have developed the world's first AI model for automated design of ultra-thin optical elements. It helps find more precise solutions for flat optics, which are used in VR devices, sensors, medical equipment, and photonic chips.
The new generative model is called MetaDiT. It creates metasurfaces – ultra-thin optical structures that control light at the nanoscale.
MetaDiT operates in two stages. First, the system observes how light should behave – where it is stronger and where it is weaker. Then, it gradually selects the necessary nanostructure from random elements until a shape that produces the desired effect is achieved. Simultaneously, it immediately calculates the main parameters – thickness, distances between elements, and material properties.
This approach allows for more precise designs of flat optics for various devices – from VR to medical systems.
The work was carried out for about a year and a half at the joint research center at Harbin Engineering University in Qingdao. The article has already been accepted for the AAAI-26 conference in Singapore – one of the most prestigious global platforms for artificial intelligence.
Creating ultra-sensitive optics is extremely challenging. The slightest deviation in shape or material can completely alter the behavior of light. Therefore, such elements were previously designed with great difficulty.
