Invited/Optics Frontier Conference: Advanced Photonics

1.Institute of Materials Research and Engineering,ASTAR

High refractive-index nano-antennas capture the best of both worlds – the strong interaction with light comparable to that of plasmonics and the low absorption loss of dielectrics. In the past few years, increasing interest has been seen toward discovering new properties and new applications of these nano-antennas, enabled by the advancement of nano-fabrication techniques. Many useful devices, static or dynamic, have been demonstrated. In this talk, I will start with a review of the development of technologies based on dielectric nano-antennas in our group. Then, I will elaborate on our recent push on large scale metalens fabrications and the latest development of spatial light modulators based on tunable dielectric metasurfaces.
