Abstract

2D layered materials have been intensively studied as candidates for next-generation nanometric optoelectronic devices due to their strong light-matter interactions resulting from 2D quantum confinement. Thus, metalenses based on 2D materials have demonstrated attractive properties, such as nanometer thickness, high focusing resolution and efficiency, high mechanical strength and flexibility, and fast and low-cost fabrication process, and can be applied in harsh environments for different applications. Here we demonstrate the recent advance in 2D materials metalenses, which can achieve diffraction-limited imaging, nanoparticle tracking with nanometer precision, and broadband in-situ zoom imaging with varifocal graphene metalenses.
