Subwavelength Structure

Subwavelength structures manipulate light at scales smaller than its wavelength, enabling unprecedented control over electromagnetic waves. Current research focuses on developing efficient inverse design methods, employing artificial intelligence, particularly diffusion models and deep learning, to directly map desired optical properties to the required subwavelength structure geometries. This allows for the creation of advanced imaging systems, such as diffractive optical processors using solid-immersion layers, achieving subwavelength resolution in applications like bioimaging and sensing. These advancements significantly accelerate the design and development of novel photonic devices and improve the capabilities of existing technologies.
