Abstract: This talk presents our research on topology optimization of micro/nano optics and its experimental verification. By focusing on the key scientific problems including the innovative design with synthetical consideration of the micro/nano scale effect and fabrication constraint, for dielectric structures of nano-optics, we proposed a topology optimization method based on a compound regularization procedure and spitted wave equations, and overcome the challenging problem of the high numerical-aperture metalens in terms of process reliability; for metal structures of nano-optics, we proposed a topology optimization method based on the hybrid material interpolation, and overcome the limitation on the field strength enhancement of the localized surface plasmonic resonance; we developed the topology optimization method of fluid dynamics, solved the challenging problem on the design of microtextures at liquid/solid interfaces, proposed the topology optimization method implemented on manifolds and extended the design space of topology optimization onto two-dimensional manifolds.
