Abstract

Sub-wavelength structured planar lenses known as metalenses are leading to a fundamental breakthrough in optical design with the emergence of high-end and multifunctional flat optical components that circumvent limitations in refractive optics. I will introduce our recent advances in broadband high-efficiency metalenses showing an average efficiency of approximately 90% for a wavelength bandwidth of 470 nm to 700 nm. Additionally, using metalenses as an essential core element in optical systems for polarization imaging and achromatic imaging is discussed.
