Adding extra dimensions to dielectric nanostructures – revolutionary building blocks for nanophotonics

This project will explore the light-matter interaction in the nanoscale, where nanostructures are fabricated with a high resolution and spatial complexities in all three dimensions (3D). Moreover, the optical behaviors (like polarizations and photonic band gap) can be actively tuned by introducing phase change materials or external electric modulations. Benefiting from an unconventional 3D fabrication technique that has been developed recently by the project leader, this project can give deeper insights into nanophotonics in a complex medium, and bring new possibilities to some cutting edge research topics like 3D photonic topological insulators and 3D dielectric resonators in visible wavelength. A further development of the emerging technology can also benefit a wide spectrum of fields like nanoelectronics and nanomechanics.
